There has been an accident. A three-car electric multiple unit, travelling at about 80km/h, has derailed on a set of facing points approaching a station stop. The unit was in passenger service and has remained upright and coupled, clear of the points. There are no serious injuries. The leading bogie has remained on the rails; all the remaining bogies have derailed.

It'll take me some time to respond to this batch of questions; however I tackled this question in a London Study group session some years ago and the attached Powerpoint presentation was what I used to talk around an answer to this question.
