I thought this explained why the first class coach had been marshalled towards the middle of the formation (with standard class coaches both ahead of it and behind it) but then we are told:
Were the TO to be added between the DVT and POD, that would make the five coach formation 67-TOE-TOD-SV-POD-TO-DVT which would again put the first class coach in a standard class sandwich. That would leave passengers in the TO having to walk through first (which I would be rather concerned about doing, given the warnings in some first class coaches about not even being allowed to stand in first class vestibules if you only have a standard class ticket) to access the buffet. Surely the best formation would be whichever of the following two options ensures that the TOD is platformed:
- 67-TOE-TO-TOD-SV-POD-DVT
- 67-TOE-TOD-TO-SV-POD-DVT
And if the sets all have SDO now, why can they not increase to 5-car yet (particularly as they have had to do some shunting to replace the TO with the TOD anyway - why not just add the TOD to the set to increase capacity sooner rather than swapping them)? Sorry, I've probably asked this before (and probably got an answer too, but I've forgotten it).
Re. the external livery, both Grand Central (black sets) and StagecoachVirgin EastCoast (red/white sets) don't appear to have used the standard yellow stripe to identify first class on their mark 4 sets (although Grand Central seem to have it on their mark 3s). However, you can still tell a first class vehicle with both liveries - the StagecoachVirgin (VTEC) livery has a pair of purple lines randomly running along beneath the window band on the first class vehicles and the Grand Central livery has a sort of dull golden colour on the doors of first class coaches instead of the silver/white on the standard class doors.
