Are contra-peak Charing Cross to/from Lewisham trains envisaged?

I can't see how the evening peak can be run without them. With 28 tph from
Charing Cross there'll have to be 28 tph contra-peak (passenger or ecs) into
Charing Cross. So there'll be 28 tph each way through Tanners Hill Junction.
Some of the down trains will run to Lewisham, and have to cross the Up Fast
Line at Tanners Hill Junction. Realistically the only way of doing this is
to have trains from Lewisham to Charing Cross parallelling them through the
junction.

The 1976 evening peak timetable included 28 tph from Charing Cross, but of
these 3 crossed at Spa Road and ran via Greenwich, and 3 crossed to the Slow
Line at North Kent East, so only 22 ran on the Fast Line at Tanners Hill
Junction.6 of these ran via the spur. On the Up Fast there were 22 trains
through Tanners Hill Junction (these had to cross the 6 down via the spur),
with another 3 coming via Greenwich and crossing at Spa Road.
