Haughley Junction Improvements

This article in the East Anglian Daily Times is entitled New Tracks. New Platforms At Ipswich Station. And Faster Trains. Will East Anglia’s Rail Bosses Be Able To Deliver?.

This is said about Haughley Junction.

Mr Bradley said improving Haughley junction, making it a full double-track junction, would mainly benefit cross-country services but it would reduce a potential main-line bottleneck.

This Google Map shows the junction.

Haughley Junction is towards the top of the map.

  • The track going vaguely to the North-West goes towards Bury St. Edmunds, Newmarket and Cambridge.
  • The track going North goes to Diss and Norwich.
  • Ipswich is to the South.

Work is eased by having a large space on the Eastern side of the junction, but where the railway crosses Station Road, there is a level crossing, which is to be removed.

It looks to me, that this is one of those projects, that can grow to be very complicated.

Consider.

  • Will a flyover be built or will it be a flat junction?
  • Will the main Ipswich-Norwich line be moved to the East.
  • How will engineers deal with the level crossing closure?
  • Will any electrification be added towards Cambridge?

With regards to the last question, it should be noted that Cambridge and Haughley Junction are forty-two miles apart.

Greater Anglia’s Class 755 trains can replace each diesel engine with a battery pack. This will be done on the South Wales Metro.

In .Battery Power Lined Up For ‘755s’, I investigate what Stadler have said about Class 755 trains running on batteries.

  • Ranges of up to forty miles are quoted.
  • Batteries could be fitted to Greater Anglia’s bi-mode Flirts at an overhaul.

I would expect that the electrification would be extended towards Cambridge by as much as is needed to make sure that battery operation between Ipswich and Cambridge is possible.

I have just flown my helicopter along the line, as far as Chippenham Junction.

  • The line splits at Chippenham Junction, with one branch going through Newmarket to Cambridge and the other to Ely.
  • Chippenham Junction is seventeen miles from Cambridge.
  • The route betwen Chippenham Junction and Haughley Junction appears to have been cleared for el;ectrification.
  • Electrification through Newmarket would be expensive, as there is a tunnel, a section of single track and possibly a station rebuild.
  • Chippenham Junction and Haughley Junction are about twenty-five miles apart.
  • Chippenham Junction and Ely are about fourteen miles apart.

If I was in charge of this project, I would certainly investigate the possibility of electrification between Haughley and Chippenham Junctions

  • Class 755 trains with batteries would be able to run between Chippenham Junction and Cambridge or Ely on battery power.
  • The East West Rail Consortium is proposing a Park-And Ride station, which could be called A14 Parkway.
  • How much money would train operators save, if this section was el;ectrified?
  • Power for the electrification would be picked up at Haughley Junction.

Would it allow tri-mode Class 93 locomotives to be able to go between Felixstowe and Ely only using a relatively small amount of diesel compared to a Class 66 locomotive?

I also think that electrifying between Chippenham and Haughley Junctions is low risk electrification.

  • The route has been gauge-cleared.
  • Thee new Class 755 trains can run without it.
  • On the other hand they will run more efficiently when it has been installed.
  • It would enable Class 93 locomotives to run on electricity.

Too many electrification projects need new trains. These are already in service.

Conclusion

There is more to this project than meets the eye.
