This leaves the Maryland problem (note that Maryland does not appear
on any of the Crossrail maps ...)

Or are they planning to close Maryland - and if so, why? Is to too
close to the planned portal, or do they just not think it's important
enough to add an extra minute to the journey?

Crossrail trains will be 10 cars. Maryland only has room for 8 with no
room to extend at either end (there are road bridges).

Moreover, presumably, road bridges that can't be widened?

Therefore Crossrail trains can't serve Maryland.

I can see three possible solutions to this problem:

b) Fit selective door opening and stop Crossrail services but only open
the doors on the front 8 cars. (the 375 fleet in Kent makes extensive
use of selective door opening, as does the existing underground, so
there are plenty of precedents)

Hang on, though; on the tube, it's just the last door in each end car that
doesn't open, so anyone in those cars who wants to get off can do so via
another door. If you've got two whole cars with no open doors, anyone
who's in one of them and wants to get off is probably buggered.

What happens in Kent?

And don't forget:

d) Park the train with the first eight carriages in the station, open the
doors on those, let people off, close them, drive the train forward two
carriage lengths, park again, open the back eight doors.

Or even:

e) Kill all HMRI and HSE inspectors, bring the train in so that the first
eight cars are at the platform, open the doors, then drive forward very
slowly, opening each door as it reaches the platform or closing it as it
passes beyond it, until the last car is at the platform, then close up and
drive off. Fast.
