DfT Thameslink Stock Specification

[JamieLei]

It's been announced that IEP trains would run to Cambridge, and then probably onwards to Kings Lynn. Thameslink cars will probably be used for outer-suburban runs, while existing express stock will probably run the fasts to the periphery of the London Commuter Belt.

One assumes there's a degree of flexibility in the spec, (or that Alstom have shot themselves in the foot again)...

Looks interesting - 11 x 22m carriages!

Articulated carriages are already used elsewhere I believe

[Ameecher]

No trains in the UK used articulation and to the best of my knowledge, especially not off-set articulation.

I think its used in Australia....

No trains in the UK used articulation and to the best of my knowledge, especially not off-set articulation.

Apart from Gresley's articulated carriages on the LNER of course, and more recently the Class 373...

I think the APT was articulated too but the less said about that the better...

Not sure what the difference between these examples and off-set articulation is though.

Well ok, I suppose I was referring to current stock (I don't know why but I don't class 373s in the British stock list!) From what I've gathered from reading Alstom's junk about this, unlike articulation like on a 373 where a bogie is located between the two carraiges it'd be under one of them entirely. Similar actually to the Sheffield supertram units that have 3 parts, the centre part having 2 bogies but the outer cars only having bogies at the front ends with the rear being supported by the middle car. Interesting theory but will mean higher axle weights.
