Hi Cornish trans jez, Hope you model of Euston works out well. Bit of info that may be of use ( apologies if its already been mentioned earlier) The DVT sets were mostly operated with the DVT/ first class at the London end of train, , for 1st passengers not having to walk so far, and also to facilitate any loco changes that took place, which quite often happened when I was a driver at Euston in the 90's. On occasions, mostly at weekends some sets could get turned in the Birmingham area which would have the loco London end and DVT country end. The sleeper services varied, but when it was Scotrail, and motor rail service ended the Glasgow/Edinburgh trains and the Inverness, Aberdeen & Fort William trains were combined and were loaded to 16 coaches. usually worked with class 87's . In early days of Privatisation, EWS supplied the loco's class 90's and worked by Virgin Trains drivers.
Regards
John
