The Woolwich ferry provides a really important service and its going to be extremely busy over the Olympic period. There are going to be days where the workforce are going to be stretched to the limit.

A spokesman for Southern Railway said the delays at London Bridge were caused when a train was signalled into the wrong platform at the station.
The 10-carriage train arrived at a platform intended for trains with eight carriages.
The spokesman said: "It meant the train had to be sent back along the track, which caused congestion."
Passengers faced delays of about 20 minutes before services returned to normal at 8.30am.
