QUOTE (Jennings @ 21 Nov 2007, 18:59) <{POST_SNAPBACK}>Ah yes - They sent a copule of the diesels to assist to drag it out the tunnel but those failed en route i think (If thats the right incident i'm thinking off???).

PS: The diesels i am referring to are those which are designed to work in the tunnel on engineers trips and don't venture out of the channel tunnel operating area.
These are the ones you're talking about.

EuroTunnel diesel.

They are designed as permanently coupled dedicated locos, too specialised I would imagine?

As Eurostars consist of two half sets with independent power, a certain amount of redundancy is built in.
A failed unit would remain powered by the other half. Mechanical failure preventing movement would be another matter, but would equally apply to any train.
A failure in the tunnel that meant the train was stuck, would probably lead to splitting the set with passengers being moved into the working half. Other than that it may be an evacuation? I believe they periodically rehearse this?

Could it be that reliabilty figures demonstrate that dedicated "Thunderbirds" along HS1 are not required?

QUOTE (Ravenser @ 25 Nov 2007, 00:07) <{POST_SNAPBACK}>I can't remember when I last heard of an EMU being rescued by a loco (Pendolinos aside - they don't work in multiple).
Although Pendolinos don't work in multiple, I'm sure a test was conducted where a Pendolino rescued another (simulated dead) Pendolino successfully.
I think they did this on the Lake District section of the WCML, presumably as a worst case scenario.
It happened 3 or 4 years ago and was widely reported in the Rail press at the time.
