How Would IPEMUs Fit With The East West Rail Link?

I feel very much, that IPEMUs or battery trains are very much going to be a part of the UK rail network in the next few years.

When I was writing Are The TOCs Arguing Over The Class 387 Trains?, I kept coming across the Oxford end of the East West Rail Link, so I got to thinking how IPEMUs would fit in with the line.

Will the Line Be Electrified?

The Government certainly thinks so, as Wikipedia reports.

The Secretary of State for Transport, the Rt. Hon Justine Greening MP, today announced that the Western section of East West Rail (EWR) will be part of the government’s strategy for rail transport, confirming not only funding for the project but also for electrification of the Oxford to Bedford part of the route. EWR will provide an electric link between the electrified Great Western, West Coast and Midland main lines. This further investment in the project upgrades it to form a key part of the new ‘Electric Spine’ passenger and freight route between the South Coast, the East Midlands and Yorkshire

But I’m not sure.

  • Will freight operators pay out for new electric locomotives or will they stick with their old noisy and smelly Class 66 locomotives? I’m afraid most will stick with what they’ve got!
  • The new Class 88 electro-diesel locomotive will be delivered this year and what effects will they have on locomotive procurement?
  • One of the major intersecting lines is Chiltern, which is not electrified. Will the Chiltern Line be electrified to make things easier? It could be! But I doubt it!
  • After the fuss about the aesthetics of the electrification on the Great Western Main Line, that I wrote about in Aesthetic Problems With Overhead Wires On The Great Western, I have a feeling the natives might object.
  • When they see the total bill for the Great Western Electrification, will the Government have second thoughts about electrification?

I think the line will eventually be electrified, but it may not be built with electrification, just as the first section between Bicester Village and Oxford Parkway stations was.

It would be built however, so that it would be easy to electrify in future.

  • All over-bridges would have sufficient clearance for overhead wires.
  • Space would be left for overhead gantries and other essential electrification equipment.
  • Piles for gantries might even be put in.
  • Everything would be properly documented.

Too many railway lines in the past were just built and assumed no improvements would ever be made.

Connection To Existing Electification

One of the most expensive items in an electrification scheme can be connecting the new wires to a suitable electricity supply.

This is why Crossrail and the Great Western Electrification share a sub-station to the West of London.

The East West Rail Link crosses a succession of lines at its Western End from Oxford to Bedford. In order from the West they are.

Only the Chiltern Main Line will not be electrified, when the Oxford to Bedford part of the link opens.

The route from Bedford to Ipswich and Norwich is not fully defined yet, but it is likely it will cross these electrified lines.

So the link, isn’t short of connectivity to electrified lines, which will help with full electrification.

The Route

This map from the East West Rail Link web site shows the route.

Starting from the West stations are.

It’s quite a few stations, many of which are simple affairs in rural locations.

IPEMUs And The East West Rail Link

Proposed services when they start in 2019 will include.

  • Bedford – Oxford – Reading
  • Milton Keynes – Oxford – Reading
  • Milton Keynes – Aylesbury – Marylebone

The first two services could be easily run by IPEMUs, but the third might need other arrangements.

According to the latest Great Western electrification schedule Oxford is not scheduled to be electrified until June 2019, so as I believe that Oxford will be reached by IPEMUs until that date, I suspect that we’ll see IPEMUs on the line, as they will be able to easily bridge the fifty mile electrification gap between Didcot on the Great Western and Bletchley on the West Coast Main Line, charging their batteries at both ends of the route.

The London to Aylesbury Line is thirty-nine miles of which sixteen miles are owned by the London Underground. Could it be if the line between Aylesbury and Winsford were to be electrified and some form of third-rail power was made available on the sixteen miles of the London Underground, that IPEMUs could work the services between Marylebone and Milton Keynes?

If they can’t, then it will be more diesels from Chiltern. But Chiltern’s ambitious nature, says they would prefer some form of electric train.

If the lines were eventually to be fully electrified, the IPEMUs would still have a valuable part to play as their self-contained regenerative braking would mean that the power supply wouldn’t have to be able to accept a return current, which lowers the cost of electrification.

Conclusions

IPEMUs will have to play some part in providing services on the East West Rail Link, because of the late running of the Great Western electrification.

Also with some selective electrification, Chiltern could use them for a service between Marylebone and Milton Keynes.

As these trains can provide a service on the whole line using existing electrification, the electrification of the East West Rail Link should be enabled but delayed to allow wires to be put up in more important places.
