Ahh. I knew there was something stopping me sleeping...
That new plan has resurrected a vague idea to do Birmingham New Street as a 7mm micro layout. A lot of trains terminated or reversed so a loco and half a coach* could appear, the loco detach, the coach eventually disappear etc. Maybe a single unit leave the other way occassionally.
*If I make a mk1 BG out of two Dapol brakes cut in half, I could literally make a couple of 1 bogie dummy coach ends with the leftovers and keep the hidden section really short.
Carlsberg dont make photo planks, but if they did.....
