Should We Renationalise the British Railways? That's Not the Right Question

Let me start with a surprising statement: the Department for Transport (DfT) now exerts far more control on the British railways than they ever have before. And yet, the railways are more "privatised" than they have been since the start of the First World War. Welcome to the confusing, contradictory world of Britain's rail industry.

British Rail was privatised in 1994, and ever since there have been calls to renationalise it. But the biggest change wasn't that the railway network was privatised; the biggest change was that it was fragmented, broken down into literally dozens of separate companies all ostensibly trying to work together to provide a unified National Rail network, all the while each trying to extract their own little margin of profit.

What this means is there isn't a "British Rail PLC" that can simply be renationalised, but rather a whole multitude of companies which would need to be recombined were we to try and renationalise the railways.

What are these companies? In a nutshell, the privatised railway can be explained as follows: one company owns the tracks, three more companies own the trains, and about 20 other companies run the passenger services. In theory, they all work together to move passengers around, but are also in competition with each other...

How did we end up with this mess? To answer that we must turn to politics. In 1992, the Conservative Party included in their election manifesto that they'd privatise the railways if they won the election. To the surprise of everyone, they won, and then had to make good on that election promise. In 1993, the blueprint was laid out for privatisation: although ostensibly designed to generate competition between the different sectors, the cynic in me wants to believe that the government knew they'd probably lose the next election (they did), and thus set about privatising the railway in a way that couldn't ever be undone. (Nonetheless, I am reminded of the aphorism: "never assume malice when stupidity will suffice".)

The tracks, points, signals and stations were sold off to Railtrack. Railtrack were a profitable company, listed on the London Stock Exchange and part of the FTSE 100 index. But after a litany of accidents, including Hatfield and Potters Bar, Railtrack's assets and operations were transferred to the state-controlled not-for-profit company Network Rail in 2002.

Meanwhile, the trains were sold off to three rolling-stock holding companies (ROSCOs): Angel, Eversholt and Porterbrook. Between them, these three companies own practically all the trains, locomotives and carriages used on the British railway network, being leased back to the companies that operate them. In other words, all the trains that used to belong to British Rail were sold off, and about 11% of the ticket price you pay goes to leasing them back from the ROSCOs! And, unlike Network Rail, the ROSCOs are very definitely private companies and all make a tidy profit.

Most importantly, though, privatisation created 25 train operating companies (TOCs): each part of the country was carved off into a separate franchise, and each was awarded separately to be run by a private company. Each franchise controls the drivers, guards and other operating staff, and is responsible for running the day-to-day service with rolling stock leased from the ROSCOs. Minimum numbers of services per day are specified (usually quite tightly) in the franchise agreement, ensuring that passengers are provided with the service they expect.

One of the aims of privatisation in this form was competition: different companies should "compete" for passengers, driving down prices while improving quality. But that doesn't really work on a railway network with limited capacity, and with a complicated interwoven timetable. In many cases there's more than one company on each line - for example, both Virgin Trains and London Midland operate services on the West Coast Main Line out of London Euston to Watford, Milton Keynes, Rugby, Birmingham and beyond - but there are only a limited number of trains that can be run.

So how do they decide who gets priority? The short answer is that Network Rail does. Each TOC bids for "paths", much like air-traffic control slots, to run a train at a particular time, and then Network Rail decides which paths can go to which operators, and effectively the actual timetable is written, as a whole, by Network Rail. In cases of dispute, things can get referred to the Office of Rail Regulation; sometimes the dispute is resolved by the DfT specifying the exact timetable. This means that the DfT can specify exactly how much competition they want (often none at all).

Perhaps the most laughable way in which this fragmentation manifests itself is when trains inevitably get delayed. If London Midland say to Virgin, "Oi! You delayed our train!", it's not really good enough if Virgin just mumble "Sorry...". No, this is a commercial railway where London Midland must be compensated for the delay caused by Virgin. As a result, Network Rail employ hundreds of train delay attribution clerks, whose entire job is to monitor delays to trains and attribute every minute of delay to a specific cause, and thus determine who pays the compensation. (Operators get compensated when a train is delayed by just 3 minutes; sadly they have to be delayed by 30 minutes for them to pass such compensation on to the passengers.)

That basic structure has been with us now for 20 years, since privatisation took effect on April 1st 1994. There are a lot more details - such as all the subcontractors employed to clean the trains, run the catering services, upgrade the tracks, design the signalling systems - and I'm ignoring freight trains and open-access operators, but you get the picture: the railways no longer function as one, but rather as a myriad of separate companies.

In a small number of cases, that's led to a dramatic improvement in services, particularly with CrossCountry Trains, the long-distance services such as Bournemouth-Manchester and Plymouth-Edinburgh which avoid London and instead pass through Birmingham New Street. Under British Rail, CrossCountry was always the Cinderella of the network, passed from pillar to post with no investment to speak of for decades; with CrossCountry as a separate franchise, Virgin were able to dramatically improve the service. Although, it is now a victim of its own success and the trains are too short, and no-one wants to subsidise lengthening the trains...

And there lies the rub: subsidy. Ever since the then-Transport Secretary Barbara Castle decided in 1968 that some lines could remain open even though they would require permanent subsidy from the Treasury to operate them, all political parties have accepted the principle that the railways should be subsidised by the government. Even as privatisation was enacted, it was accepted that the franchises would, in many cases, require government subsidy to operate; conversely, some of the more lucrative franchises (principally long-distance inter-city operators like Virgin and GNER/East Coast) were required to pay premiums back to the Treasury. This ensured that the principle of cross-subsidisation - where lucrative services propped up loss-making ones - continued as it had done for years.

Of course, when it was all one British Rail, there was no profit to be made; every penny of subsidy went towards improving punctuality and upgrading services. But with the railway fragmented into lots of pieces, allocating subsidy is all of a sudden a trickier job. Previously the job of dishing out money to individual regions or services was the job of the British Railways Board, which operated at arms' length from the DfT, much like today's Network Rail. But without the BR Board, that function is instead fulfilled by the Department for Transport itself.

In other words, the DfT is now the one deciding that, for example, Manchester Piccadilly gets two extra platforms and freight trains to Southampton should be electrified, and that reopening the line between Lewes and Uckfield will have to wait. Network Rail can have their own say on small-scale track improvements, but for anything large-scale or anything involving a significant timetable change, it's the DfT's decision. Even under BR, the DfT didn't have this much control in the day-to-day running of the railway.

Yet, conversely, with dozens of companies involved in running the railways, all trying to extract a profit, the railway is nearly as privatised as it was in the days of Stephenson and Brunel. And while privatisation usually makes things more efficient and reduces costs, in this case the fragmentation has meant that costs spiralled massively, to guarantee each of the companies involved a share of the profit.

Where does this profit come from? Government subsidy (at least in part). Whereas subsidy to British Rail only rose above £1 billion per annum in 1991 (and even that was partly due to the recession at the time), in 2006-07 the total subsidy to Network Rail and the TOCs stood at a whopping £6.3 billion. To be fair, that's come back down to about £4 billion per annum as at 2012. (More figures here.) Nonetheless, what that means is that subsidy to the railways today is about three or four times what it was when it was nationalised; even adjusting for inflation, subsidy has at least doubled in real terms since privatisation.

The reasons for that are not at all clear, and nor is the solution. While some of that subsidy is due to the fragmentation of the industry, some of it may be due to the boom in passengers: passenger numbers troughed at about 700 million in 1995, but have since climbed to over 1.4 billion in 2012. As a result, the railways are carrying more passengers per year than it has since before the Second World War, and moving more people costs more money. Some of the increase in subsidy is also down to long-overdue maintenance; British Rail postponed a lot of maintenance (often even simple things like replacing worn-out track), and Network Rail is having to work overtime to clear the backlog.

It's also important to remember that, in spite (or perhaps in some cases because) of the fragmentation, the railway network has improved immeasurably in the last 20 years. The West Coast Main Line now gets 125mph trains every three minutes, and it takes less than an hour to get from Coventry to London (though the upgrade did cost £9 billion). And as my recent posts have shown, we're currently in the throes of one of the biggest programmes of upgrades to the railway network in decades, with Crossrail, the Thameslink Programme, Great Western electrification, the Northern Hub and the Electric Spine. Those upgrades don't come cheap.

On September 1st 2014, Network Rail was reclassified as a public sector body, meaning that its debt (some £34 billion) counted towards the national debt for the first time since privatisation. That debt is an inevitable side effect of wanting investment now but wanting to pay later; railway investment is a pretty safe bet, because there will always be lots of passengers to move, and if you can move them more efficiently then so much the better. (Incidentally, one of the few reasons the debt was kept off the public sector books was that Gordon Brown didn't want to breach his rule that the national debt should not exceed 40% of GDP, though that went out the window in the financial crash of 2008.)

In practice, this means very little else; the DfT will continue to exert the same control over Network Rail as they have done for years, and Network Rail will continue to ask for more money for improvements. It will probably mean that the salaries of the big bosses at Network Rail will have to fall in line with public sector limits (current chief executive Mark Carne receives an annual salary of £675,000), but the day-to-day running of the railway will change very little.

Does it perhaps signify a change in ethos at the Department for Transport, a desire to move towards a renationalised railway? I don't think so, or at least not under the current government. Indeed, the current government is trying to get East Coast, which was temporarily renationalised when the franchise held by National Express went bust, back into the private sector by the next election.

The Labour Party, however, have suggested that a state not-for-profit firm (such as that which currently runs East Coast) should be allowed to bid for franchises when they come up for renewal. Personally I think that's just making a dog's breakfast of a railway network even worse by trying to partially renationalise bits by the back door: it's not clear that partial renationalisation is actually better, since then you might have not-for-profit companies trying to compete with the likes of Virgin Trains, and that isn't likely to end well (for anyone).

Ultimately, no government since John Major's has had the guts to take any fundamental policy decisions with respect to the structure of the railway network; they've tinkered at the edges, but the railway is still basically that given to us in 1994 at the time of privatisation. A full renationalisation might bring costs down and thus enable more investment in the infrastructure for the same level of subsidy. But even British Rail struggled to find the right structure for the railways: they tried organising it by region, but in the 1980s moved to "sectorisation", where InterCity, Network SouthEast and Regional Railways were all subordinate only to the top management, without regions to get in the way.

Ever present in British Rail, though, was the knowledge that the tracks cannot be maintained without knowing what trains have run over them, and trains cannot be maintained without knowing where they've been. Perhaps the oddest thing about privatisation is that it has separated track from train, with virtually no "vertical integration" of tracks and trains for nearly 20 years. In recognition of that, South West Trains are experimenting with a "deep alliance" with Network Rail's Wessex Route: since 2012 the track and trains on the lines out of Waterloo have been brought into one management structure, for the first time since the days of British Rail.

But that won't work everywhere: even within the Wessex Route there are other trains run by CrossCountry, Southern and First Great Western, as well as a multitude of freight trains serving the port of Southampton. Try and make a vertically integrated railway around Birmingham or Manchester and you're in for a world of trouble, such is the number of different operators in the area. Indeed, the success of CrossCountry is precisely because there isn't vertical integration. Sadly, there isn't an easy one-size-fits-all solution, as British Rail found.

Let me be clear: on this occasion I don't want to try and argue either for or against renationalisation. My point is that renationalisation would require reintegration of the myriad companies that were created at privatisation, and that would bring about a complete restructuring of the railway. In other words, renationalisation is not something to be undertaken without a lot of thought put into the structure of any renationalised railway and - more importantly - how we get there.

Putting the railway network back together could be done: it would probably require the state buying out the train operating franchises (or letting them expire), getting the trains back into public ownership, and instituting a management structure more like British Rail. But that kind of shake-up would require more political will than I think any government is likely to want to expend on railways: unlike privatisation, which was achieved within a single parliament by a partisan government, reintegration and renationalisation might require a commitment over one or more decades to see it through.

For all its faults, the privatised railway has presided over one of the biggest booms in passenger use in history. After 20 years of getting used to a whole new structure, the rail industry has found its feet again, and a huge programme of upgrades, new lines and electrification is underway, with £30 billion being spent over the next five years or so to dramatically improve the railways in a way not seen for generations. Would that investment have come under British Rail? Possibly. But when the current structure has given rise to that much investment, it's hard to argue that now is the time for a fundamental shake-up of the railway industry.

There is undoubtedly scope to improve the organisation of the railways, but I think it's best achieved by the typical chant of the Englishman:
"What do we want? Gradual change! When do we want it? In due course!"
Whatever happens, though, I sincerely hope that it's not driven by blind ideology with no regard for the structure of the industry. Full-scale renationalisation rammed through without a plan for how to reintegrate the railways would be no better than John Major's privatisation. And until someone comes up with a detailed plan for how to renationalise the railways, the question of whether or not we should renationalise them is impossible to answer.

What is... the Electric Spine? (Or, Why Freight Trains Matter to Everyone)

The "Electric Spine" is a plan to electrify two key rail arteries from the port of Southampton to the north of England (via Nuneaton and Sheffield), creating an electrified trunk route avoiding London, principally for use by freight trains. The plan is, as yet, still not finalised; but it promises to have a huge (yet also subtle) impact across the country. So while this blog usually focusses on passenger trains, for this post I'd like to delve into the world of freight trains, and explain why we're spending over a billion pounds so that freight trains can run a bit faster...

Once upon a time, almost all freight traffic in Britain was moved by rail. While the vast majority of it is now hauled by lorries instead, for some traffic (e.g. coal) rail is still the "right" way to move it around the country. This is especially true of long-distance flows: for example, for taking containers from Southampton to Scotland, or cars from Merseyside to Dagenham Dock, rail has the advantage of bulk and speed that road just can't match. Indeed, container traffic has seen a marked shift from road to rail in recent years, and the challenge for the rail network is how to accommodate it.

Unlike passenger trains, which can be broken down into discrete services, even the destinations of freight trains can vary from day to day. Passenger trains between London and Birmingham are completely segregated from, say, passenger trains between London and Dover; in that sense, the electrification of the passenger rail network can be - and is - broken down into discrete chunks, one main line at a time. Freight trains, though, are much less frequent and tend to run to a wide variety of destinations, over a variety of different routes according to where there's capacity.

By its very nature, then, the network used by freight trains is huge and sprawling: indeed, it's quite hard to find a significant part of the network that isn't used by freight trains at all. As a result, while some freight trains running on key main lines can be hauled by electric locomotives, the vast majority of freight trains remain hauled by diesel engines, even when some of the route has electric wires, because having to stop and change engine takes too much time. And that's unlikely to change until a significant portion of the freight network is electrified.

So what is driving plans to try and do just that? The key advantage of electric freight trains over diesel ones is acceleration. Freight trains are mostly limited to 60mph, and while some container trains can manage 75mph, electric haulage can't really improve that. What it can do, though, is dramatically improve acceleration, so that when a freight train has to run between two passenger trains, it doesn't need as large a gap. Quicker acceleration, more capacity. Crucially, though, not just capacity for freight trains but also for more passenger trains.

This is especially true on mixed-traffic lines, where passenger and freight trains have to share the same tracks. For example, while the south end of the WCML has four tracks, north of Preston it's two tracks all the way to the outskirts of Glasgow. In particular, over Shap in the Lake District, where the WCML runs roughly parallel to the M6, the two-track line threads its way between the hills with gradients as steep as 1 in 75. For a 4,000-tonne freight train, 1 in 75 is a big problem! However, while diesel trains are limited by how big an engine they have and how much fuel they can carry, electric trains are basically limited only by how much current they can draw.

The difference between electric and diesel freight trains over Shap can be summed up as follows: from Preston to Carlisle (about 90 miles), a freight train hauled by an electric locomotive generally won't have to stop to be overtaken by faster passenger trains, while a diesel train almost certainly will. Having to have the freight train slow down, pull into a loop, wait to be overtaken, and then start up again costs a lot of time and capacity; converting diesel freight trains to electric over Shap would significantly increase capacity on this very mixed-traffic line.

The "Electric Spine" is the first major project in trying to convert freight trains to electric haulage: the broad intention is that almost all long-distance container trains to and from the port of Southampton will be able to run with electric traction. At this point, though, while the project is committed by the government, it's still being developed by Network Rail, and is unlikely to be fully complete before 2025. Indeed, more than any of the other "big projects" I've discussed recently, the Electric Spine poses the biggest unknowns: there are things in the plan that have never been done before.

Let's return to electrification in general (see my earlier post if you need a refresher). There have been many different voltages and both overhead wires and various forms of third rail in use for electric trains over the years, but two systems remain in widespread use in the UK: 750V DC third rail, mainly south of London, and 25kV AC overhead wires, mainly north of London. Because most passenger services are self-contained, most electric trains only need one kind of electric equipment, and for the small number of services (mainly Thameslink and London Overground) which use both, the trains can be fitted with both systems.

Both systems have advantages and disadvantages: third rail systems are better suited to dense suburban networks, while overhead wires are better suited to long-distance traffic. That said, most would agree that overhead wires are better than third rail - and if the network south of London were being electrified today there is no question that it would be done with overhead wires. The principal problem with third rail is that, because the rail is so close to the ground, the voltage can't really be made higher than 750V. (The National Grid uses 275kV DC to transmit electricity around the country, but the wires are high in the air.)

In order to provide enough power through the third rail, the current has to be higher than it would in overhead wires (power is current times voltage), and as a result a lot of power is lost in transmitting it down the rails; this means third rail requires lots more substations to provide enough power. In particular, providing enough power through the third rail to permit electric locomotives to haul freight trains is hideously expensive, and while it can be done, there are only a couple of routes which have been upgraded to provide enough power, namely those connecting London to the Channel Tunnel.

And here we encounter the major problem with the Electric Spine: Southampton is already electrified... with third rail. The plan for the Electric Spine thus calls for something which has never been done on this scale: the conversion of the line between Basingstoke and Southampton from third rail electrification to overhead wires. While this means freight trains will be able to run on overhead wires all the way to the docks at Southampton, the existing passenger trains which run between London and Weymouth would be required to change from third rail to overhead wires at Basingstoke and back again at Southampton.

For the sake of convenience to passenger trains, you might reasonably ask whether you could simply have both overhead wires and third rail between Basingstoke and Southampton. Clearly it has to be possible over short distances, otherwise trains would never be able to change from one to the other. However, in the section with both overhead wires and third rail, both systems must be carefully insulated from each other in other to prevent current straying from one to the other. As such, the existing third rail equipment would have to be heavily modified; it's certainly not as easy as just adding overhead wires on top of the existing third rail.

In any case, part of the justification for converting the line between Basingstoke and Southampton is that the third rail equipment, which was installed in 1967, will need to be replaced shortly anyway. Given that 25kV AC requires fewer substations than 750V DC, it is in fact cheaper - at least as far as the infrastructure is concerned - to replace the third rail with overhead wires. But this ignores the fact that the existing electric trains, run by South West Trains (SWT), would require conversion to work on overhead wires as well as third rail. These trains are about 10 years old, and most (the Class 450s) should be straightforward enough to convert (though the Class 444s may require more work).

And here is where the ugly truth of the privatised, fragmented British railway system rears its head: who pays? The Department for Transport are happy to pay Network Rail for the work to the infrastructure, but it is not clear who will pay for the conversion of the trains. The trains are operated by SWT, but are in fact owned by the rolling stock holding company Angel Trains. Why should either SWT or Angel Trains pay to change their trains because of Network Rail's infrastructure changes?

The issue is yet to be resolved, and it's still not clear whether the line between Basingstoke and Southampton will actually be converted. I suspect it will, but I suspect the government will have to pay for the conversion of the trains as well. However, if any of the electrification projects were to run over-budget, the quickest way to save money would be to kick the whole Basingstoke-Southampton conversion into the long grass.

The rest of the Electric Spine can be broken down into four distinct chunks:
  • The section between Basingstoke and Oxford, via Reading, will be electrified as part of the Great Western Main Line electrification, associated with the Intercity Express Programme (see my earlier blogpost) - at least, the Reading-Oxford part will; exactly what will happen with Reading-Basingstoke isn't clear.
  • The section between Oxford and Bedford is unusual in that part of the line that will be electrified isn't open yet! The "East-West Rail Link" is soon to be reopened; whether it will have overhead wires from opening (in 2017) or whether it will follow a few years later (by 2019) remains unclear. (See also my earlier blogpost about a railtour along part of the East-West line.)
  • The section between Bedford and Sheffield amounts to electrification of the rest of the Midland Main Line (MML), the section between London and Bedford having been electrified in 1981 for suburban trains. This section will herald the biggest changes for passenger trains too, allowing the existing diesel trains running between London and Nottingham, Derby and Sheffield to be replaced by electric trains.
  • The section between Oxford and Nuneaton, which will probably be the last part to be completed (apart from Basingstoke-Southampton), will link Southampton to the West Coast Main Line at Nuneaton, allowing electric trains to run all the way from Southampton to Manchester, Liverpool and Glasgow. I wouldn't be surprised if this got pushed past 2020 (and it would make another easy target for cuts).
While this is a good start to an electric freight network, that's all it is: a start. For one, it's missing a key connection from Sheffield to the electrified East Coast Main Line at Doncaster. But it also leaves the other major deep-water container port - Felixstowe, in Suffolk - just twelve miles from the electric wires at Ipswich. Electrifying that branch could probably do as much for container freight as the whole Electric Spine project.

One of the other major freight projects in recent years has been to increase the number of trains from Felixstowe which can avoid London to get to the north of England and to Scotland. Currently much of the traffic runs through London: fitting freight trains through London is a perennial challenge, with most London Overground routes in fact being freight routes that some would argue would be more efficient without any passenger stations on them! In order to relieve the pressure, tunnels and bridges have been enlarged to permit container trains to run from Felixstowe to Nuneaton via Ely, Peterborough and Leicester. If that line could also be electrified, then we'd start to make major inroads into converting at least container trains to electric traction. It seems that that, however, will have to wait for Southampton to have its turn first.

Ultimately, the point of the Electric Spine is to increase capacity - both for freight and passenger trains - by using electric locomotives, with their impressive acceleration, to speed up freight traffic across the country. On the one hand, this should mean fewer lorries on the roads, making road travel easier for everyone. On the other hand, this will mean more capacity for passenger trains, and fewer delays caused by late running freight trains (hopefully). It sounds like a win for everyone - and it should be - but the devil, as usual, is in the detail. For now: watch this space.

Previous post: What is... the Northern Hub?

What is... the Northern Hub?

The Northern Hub is a £560 million project to upgrade and electrify much of the railway network in the North of England, particularly focussed on the cities of Manchester, Liverpool and Leeds. As well as electrifying over 300 miles of track, the project will unlock one of the biggest bottlenecks in the country: Manchester Piccadilly station will gain two extra platforms, and the Ordsall Chord will allow trains to run directly between Manchester Piccadilly and Manchester Victoria. All in all, rail travel in the North of England will be transformed.

You may have noticed that, so far in this series of blogposts, the projects we've looked at - e.g., Crossrail, Thameslink and the Great Western Main Line - are all in the South of England. It's fair to say that the South - particularly London and the South-East - gets more than its "fair share" of investment compared to the proportion of the population that lives there. To a certain extent, the Northern Hub will help to smooth out that imbalance.

It's important to understand why there's an imbalance in the first place: the fact is that railways are most efficient in dense urban areas and between big cities. As a result, railways naturally gravitated towards London and the South-East, meaning more people used the railways in London, meaning they got more investment, and this created a "feedback loop" of perpetual investment in the South-East to try and cope with ever-increasing demand.

By contrast, while the urban areas in the North of England have received some investment, the railways in the North don't get used as much, so they don't get as much investment, and hence their use doesn't increase as quickly. While much of the South-East has 12-carriage commuter trains into London, four carriages already makes a long commuter train into Manchester, and most platforms can't accommodate more than six. This isn't in and of itself a problem, nor is it necessarily a sign of bias in investment priorities, but it is nonetheless a reality.

However, the use of relatively short trains does make the North's trains less efficient to run: a 12-car train doesn't cost six times as much to run as a 2-car train, not least because you still only need one driver and one guard. What's more, almost all of the North's trains are diesel trains: by contrast to the South-East, where the only major commuter line which isn't electrified is the Chiltern line out of Marylebone, so far there are just a handful of electric lines around Manchester and Leeds, and (as I discussed previously) diesel trains are more expensive to run.

Happily, though, an opportunity to make the North's railway network far more efficient came when then-Transport Secretary (Lord) Andrew Adonis hit on a bright idea. He reasoned as follows: Thameslink is getting a huge fleet of new trains, meaning the 86 4-car Class 319s will no longer be required. The trains could simply be moved to another already-electrified line to displace some older trains and allow them to be scrapped, but instead Adonis decided to invest in electrifying new lines, and send the Class 319s there.

This allows lines to be electrified without incurring the additional cost of a brand-new fleet of electric trains, a significant saving. One of those lines is the Great Western Main Line, where new electric inter-city trains will replace the existing HSTs, and the Class 319s would be used on suburban services in the Thames Valley between London and Reading, Oxford and Newbury.

The GWML alone, however, wouldn't account for all 86 class 319s, so in 2009 four lines in the North-West were chosen for electrification in a phased programme:
The Chat Moss electrification was announced first, in July 2009, with the other lines following in December 2009. The initial announcement came rather out of the blue: it is not entirely clear why the Chat Moss line was chosen, but if Adonis's intention was to start the ball rolling on significant investment in the railway network across the north of England, he picked the right line! Although they initially put the plans on hold thanks to the post-election Spending Review, the new coalition government reconfirmed the plans in October 2010.

The class 319s are to be cascaded to the North-West, permitting older diesel trains (such as the dreaded Pacers) to be scrapped. All told, about 35 Class 319s will be needed across the North-West. However, due to delays in the Thameslink Programme, while the first two phases of wiring will be completed by December 2014, there will only be three electric trains available to run the local services. A further 11 will follow over the following year, which will account for all the Liverpool-Manchester and Liverpool-Wigan services, with the remainder of the trains being available early in 2017 for the completion of the third and fourth phases.

---

One of the most important diesel-operated services in the North, however, is the Trans-Pennine service between Manchester and Leeds, with five trains an hour running between these two huge cities. Most start in the west at Liverpool or Manchester Airport, while in the east the trains continue on to Hull, York, Scarborough, Middlesbrough or Newcastle. With one of the routes between Liverpool and Manchester now being electrified, and the ECML between York and Newcastle already wired, that leaves only a relatively short gap between Manchester and York; wiring that gap would permit a disproportionate number of services to be converted to electric operation.

Moreover, the Trans-Pennine services are some of the most overcrowded trains in the North, and as reasonably fast inter-urban services they are a plum candidate for investment, sure to bring more significant benefits than merely electrifying commuter lines. Sure enough, in November 2011, the government announced a follow-on to the North-West Electrification: the Trans-Pennine route between Manchester, Huddersfield, Leeds and York is to be electrified by 2018. The line from Leeds to Selby (though oddly not all the way to Hull) was added to the electrification plans in July 2012.

All the big stations along the way (Liverpool Lime Street, Manchester Piccadilly, Leeds and York) are already electrified, while Manchester Victoria will be electrified as part of the North-West Electrification, making this project relatively simple; instead the big challenge will be electrifying the 3-mile-long tunnels at Standedge (under the Pennines) without causing too much disruption.

However, before the benefits of a more frequent electric Trans-Pennine service can be realised, one of the biggest capacity bottlenecks on the network has to be sorted out: Manchester Piccadilly station. It may strike you as odd to learn that, in spite of its proliferation of short commuter trains, Manchester Piccadilly station is running more or less at capacity: there is no more room to run more trains.

Manchester Piccadilly is an odd station: it has 12 terminus platforms, all facing south, used by services long-distance from London, Bristol, Bournemouth, and Cardiff, as well as local services to Stoke-on-Trent, Crewe, Chester, Glossop and Sheffield. However, the station also has two through platforms at its west side, used by services to Liverpool, Preston, Blackpool and Scotland. That there are only two such through platforms is already a capacity constraint, and plans are in place to add two extra through platforms by 2018.

But that in and of itself doesn't solve the fundamental problem, which is that too many trains want to go through each other. In particular, all the Trans-Pennine services between Liverpool and Leeds have to cross the entire width of the station throat, from the westernmost platforms to the easternmost approach lines to the south. Trains between Manchester Airport and Leeds have to reverse in one of the 12 terminus platforms, requiring them either to cross everything on the way into Piccadilly, or on the way out. This diagram shows the problem:


Enter the Ordsall Chord. From 2016, a short piece of track will fill in the third side of the triangle in western Manchester and allow trains from Piccadilly to curve round and head through Victoria, Manchester's other major station. Once the grand centerpiece of the Lancashire and Yorkshire Railway, Victoria is a shell of its former self, particularly since the Windsor Link was opened in 1988 and many services were transferred to Piccadilly. Access between the two has always been rather difficult, and while Metrolink has made it easier, the Ordsall Chord will provide a direct rail connection between the two stations for the first time.

Once completed, it will allow Victoria, not Piccadilly, to become the hub for Trans-Pennine journeys. The Ordsall Chord will permit trains between Manchester Airport and Leeds to run via both Piccadilly and Victoria, and avoid having to reverse along the way. While trains between Liverpool and Leeds can already run via Victoria without any capacity problems, to do so requires diverting them via Chat Moss instead of via Warrington Central; coincidentally (or perhaps as a rare piece of forward planning?) the Chat Moss is the route that's being electrified, while the route via Warrington Central will remain diesel-only.

But more importantly, it will de-tangle the services coming into Piccadilly, with services to Stockport and beyond able to run completely independently of the Trans-Pennine services, bringing significant improvements in punctuality for both groups of services, as well as allowing an increase to six Trans-Pennine services per hour. This diagram shows the solution:


As a result, by 2018 the rail network around Manchester will be transformed by two extra platforms at Piccadilly, the Ordsall Chord connecting Piccadilly and Victoria, and electrification across much of the North-West and the whole Trans-Pennine route from Liverpool to Newcastle. Put it all together and you have the "Northern Hub", whose total cost is about £560 million.

The only problem is the lack of clarity in what trains will be running on such lines: the letting of new franchises for TransPennine Express and Northern Rail has been delayed until February 2016, and only once the new franchise is announced will it become clear what, if any, strategy there is for rolling stock across the North.

One possibility is that the remainder of the Class 319s, perhaps together with some of the other trains released by Crossrail and the Thameslink Programme, could be used on Trans-Pennine services. Currently, however, the Trans-Pennine services run with Class 185s, modern three-car diesel trains which are less than 10 years old, ideally suited for inter-urban services. To replace those with commuter trains from the South-East which are nearly 25 years old is clearly a downgrade, and smacks of the North being handed the unwanted old tat from the South-East.

Unlike the North-West Electrification, however, which could only be reasonably justified by the use of existing trains, it's quite possible that the new Trans-Pennine franchise will decide to order some new electric trains to run across the Pennines. This would allow some (if not all) of the Class 185s to be transferred elsewhere, and trigger a rolling stock cascade that would ensure that many areas benefit from newer trains, while allowing more of the oldest clapped-out trains (hopefully all the Pacers and possibly some Sprinters) to be withdrawn from service.

In any case, the North is getting some much-needed improvements to its rail network, including a whole new railway line, new platforms and lots of new overhead wires. While we'll have to wait and see what trains serve it, it is clear that areas which have seen little investment for over 20 years will see dramatic improvements over the next few years. It could even be the start of a whole new rail boom across the North...
