Travelling this morning on an engineering work special - which
travelled from Wimbledon to Clapham Junction via the District Line,
East Putney and Wandsworth Common - set me wondering - has this line
ever been used as a regular route? And would it be any use if it was?
I suppose it would connect Clapham Junction to the tube, but only to a
relatively remote part of it.

And do SWT services via the District ever stop at any of the District
stations? When I first moved to London about 10 years ago I recall a
train stopping at Southfields, which I suppose could be a sort of
alternative to Earlsfield. But I'm not sure if it was an official
stop or not as it was the days of slam door trains and passengers
could get off whenever the train happened to be stationary at a
station.
