It would be a handy new connection if they did. At the moment, there
are a few services which, in lieu of being ecs, just start at Hither
Green and provide extra frequency between London Bridge and Waterloo,
which is a peak flow for people going south west.

Maybe the equivalents of those will be able to divert through, and
call at, Lewisham as well.

AIUI the RUS envisages that the peak service will consist as far as possible
of the off-peak service plus peak extras, rather than what has been the case
on the South eastern network up till now, i.e. until the 1970s London Bridge
resignalling a standard pattern off-peak service but no discernible peak
pattern at all, and since the resignalling a 20-minute peak cycle (later
eased to 21 minutes when BR invented the 63 minute hour) which bears no
discenible relation to the off-peak pattern. If this is the case the
Bexleyheath route, and North Kent via Woolwich and Lewisham, will get
contra-peak Charing Cross services via the doubled Tanners Hill spur. If
they manage to get this right it will mean that the only stations not to get
Charing Cross trains, but only Cannon Street, will be the four from
Westcombe Park to Deptford, though these won't get any Charing Cross trains
at all, at any time of the day.
