The Metropolitan line will still go to Aldgate as present. The planned
service is

6tph Hammersmith - Barking
6tph Hammersmith - Edgware Road - Aldgate - Victoria - Edgware Road
6tph Uxbridge - Aldgate
6tph Wimbledon - Edgware Road

So the Circle, always crowded, will get less frequent... and the Hammersmith
branch, always roomy[1], gets a doubling of frequency. Has anyone said why
this is happening? The stuff about the Circle lacking a depot could be
solved by running Hammersmith - Edgware Road - Aldgate - Victoria - Edgware
Road - Barking at approximately the current frequency.

[1] before Westfield.... haven't used it since.
