Walking past Putney Pier at lunchtime today, I saw some publicity for a
new commuter service along the Thames between Putney and Blackfriars:

Quite good timings, given that there are three intermediate stops
(including a five-minute wait at Chelsea) but not cheap (although bikes
are carried free!).
