There might be some merit in linking the Met. and the Chiltern Network

There's barely enough capacity at Marylebone with the existing Chiltern and
WSMR services, let alone trying to squeeze in an extra four Met trains an
hour.

If you gave Amersham to Chiltern, couldn't you also give them some of the
platforms at Baker Street?

It is a pity that those empty tunnels under Lord's Cricket Ground
cannot be put to some use considering the traffic load on the Met at
that point.

If memory serves, aren't the "spare" tunnels on the wrong side of the
Chiltern line to be any use to the Met?

Could that be addressed by using some for Chiltern, then giving the
thus-vacated Chiltern lines to the Met? This would obviously take a good
bit of space on either side for the slewing of the alignments.
