As promised, a thread about a rather special train, the TMST (Trans Manche Super Train). This was the project name for the high-speed train designed to link London, Paris and Brussels via the Channel Tunnel when it opened in 1994

Based on the French TGV, the design was adapted to run in the UK where our trains are not as tall or wide.

It had to cope with 3 different power systems supplied by overhead wires or third rail (UK).
Furthermore, the signalling systems of 3 different countries and 4 networks including the Channel Tunnel would need to be used.

Suppliers from Belgium, France and the UK all contributed to the train. The front of the power car was designed in Leicester..

There were concerns that passing through the Channel Tunnel at 160 km/h would have a hypnotic effect on the driver so the cab window was made very small compared with other trains.

The train was designed to be split in two if necessary in an emergency to get out of the Channel Tunnel. Put everyone in one half, uncouple the other and off you go!

Platforms: Traditionally they are different heights in the UK, France and Belgium. Solution: 2 extendable steps. UK high platforms: Top step only. Other countries: Both steps. Clever eh?
