Won't be an 8 coach train, unless it has a guard on it all the way to Marylebone, DOO is only signed off for a maximum of 7 coaches at present i believe
DOO now operational for eight cars at BCS. Could be interesting on Tuesday morning when commuters for 5+ London trains stand waiting in their usual place and find their train whizzing past to the end of the platform.
Does that mean that all trains longer than 4 cars will stop at the far end of the platform? That'll put most of them some way from the steps from the footbridge, which will give people a shock if they're cutting it fine!
