"severe delays to prevent overcrowding"

From the Standard:


A fire at London Bridge station triggered huge delays as commuters faced misery this evening.

Services from the station were stopped for more than half an hour after the fire in the equipment room caused a signalling problem.

Delays were continuing into the night as services struggled to cope with the extra demand caused by the hold-ups earlier in the evening.

Trains from London Bridge towards Kent and other parts of the south east were affected.

The backlog led to chaos across other London stations.

At Victoria, trains were delayed and the tube station closed for a short time due to services reaching capacity as commuters travelled to the station in a bid to find an alternative way home. Twitter users also reported delays at Bank station.
