Many thanks to all who replied. I've now bought the Way Out map -
thanks, Michael. Stanfords had plenty of them in stock, even though
none of their staff seemed to have heard of it and they certainly didn't
know where I might find it.

How funny.

I'm sure it's going to be very useful though - particularly when
alighting on crammed platforms.

It is most helpful at lift stations, of course.

Unfortunately it is not accurate 100 percent of the time (probably due
to changes in station layout at some places), but it is the vast
majority of times. In addition to marking corrections, I have also added
asterisks to mine in places where there is a cross-platform transfer.
