COMMUTERS had to find alternative routes to work as knock on effects from signal failure on the Jubilee line led to overcrowding on other routes.

The signal failure at Canada Water meant more passengers than usual tried to board Docklands Light Railway trains.

The upshot was the temporary closure of the Waterloo and City line to Bank for about half an hour this morning as too many rush hour passengers poured onto the DLR from that line.
