I believe LU are considering changing the sub-surface lines. Trains
would go
Hammersmith - Edgware Road - Liverpool Street - South Kensington -
Edgware
Road where it would reverse and head back the other way. This would have
the
advantage of giving Circle trains somewhere to make up any time they
have
lost.

This is a stupid idea. It would just end up sharing terminal platforms
with the Edgware Rd District, so the amount of recovery time available
would be necessarily tiny. The route would effectively become
Hammersmith to Hammersmith with a reversing move in the middle. On
time performance towards Hammersmith would be appalling, unless an
extra wait were added at Aldgate, which rather defeats the point of
the whole exercise.

A better plan might be to replace the Circle with a Wimbledon -
Wimbledon Loop, or alternatively to run Hammersmith - Aldgate -
Wimbledon and Wimbledon - Edgware Rd - Whitechapel.

The version I've heard - admittedly only within this group - was that the
Circle, H&C and Wimbleware lines would be replaced by two services:

1) Wimbledon-Earl's Court-Edgware Road-Liverpool Street-Barking
2) Hammersmith-Edgware Road-Liverpool Steet-Victoria-Edgware Road
