I would expect the SLL service from London Victoria to be replaced by
the ELL service to clapham junction. I think the Victoria - Denmark
Hill - Lewisham service does share tracks with this in one direction
through Denmark Hill, but it needn't.

Wouldn't that leave Wandsworth Road and Clapham High Street without any
service to Central London? As I recall, there are no platforms on the
"Chatham" pair of tracks, only on the SLL pair.
