This text seems to have been written just after the Selby (or Great Heck) accident which took place in early 2001, in which high-speed intercity train operated by GNER came off the track after it hit a car which fell off a road bridge over the track. The GNER train was running at high speed with the locomotive at the end of the train pushing all coaches from behind. The discussion on this text concerns on the safety of this "push-pull operation", referring also to the Polmont accident in 1984.
