Seems like the shoegear will be easy enough to fit if Bachmann send out spares, as there appear to be holes for them.
I can't work out what coach they've used to get the toilet on one side only though on the blue/yellow one. Doesn't seem to be a disabled-only toilet coach, as per the 769, as there's a big window one side and a toilet window the other. Seems to be a standalone coach moulding, unless I'm incorrectly remembering the toilet set-up on the blue/yellow one (or at least on some of them, as YouTube videos clearly show toilets both sides).
The NSE livery one is correct, so bodes well for the one I hope to get if they make it in OO!
