More substantially, what level of demand is there for journeys from
Clapham
to ELL destinations? I can't see a direct Clapham-Canada Water service
relieving pressure on the Jubilee Line at Waterloo and I'm not sure if
changing at Clapham gets one to Whitechapel faster than from Victoria.
But even a direct train service from Clapham Junction to Denmark Hill or
Peckham Rye would be helpful compared with the current long bus ride, which
I've done a couple of times in the past week, trying to get to King's
College Hospital from near Wandsworth Common.
