A Hammersmith MP writes (in a circular email):
I believe there should be an additional station on the Crossrail
line at Old Oak to interchange with the West London Line. It is
technically possible to build this, but the economic case will
depend on the success of the Overground system.

My response:
I agree an extra station would be beneficial, but I think it should
interchange with the North London Line. New platforms could be built
on that line to interchange with Crossrail at one end and the Central
Line at the other end. The West London line already interchanges with
the Central Line at Shepherds Bush, so my suggestion would give more
new travel options.

What do the assembled experts think?

The top priority, of course, is getting Crossrail built - without
wasting time reconsidering all possible changes to the proposal.
