Marylebone ASC have a copy of the same simplifier (and swap sheets) that
the rest of the station work from, which includes Unit Diagram numbers
that tell you what *should* be on a given working.
In case of doubt, however, they will double check with the relevant
dispatcher to make sure there's enough room in the platform before
routeing a train in.
It isn't always foolproof as it has been known to have a 6 coach train
routed into Platform 4 (which only holds 5 coaches) before now, though
that *will* fit within the overlap, so the signaller can clear the route
down without delaying inbound services too much.
