Snow in London

A light dusting of snow across London today was enough to ground flights, cripple eight Tube lines and disrupt six rail networks.
The city woke up to about two centimetres of snow covering roof tops, parked cars and roads.
Eight of the 12 Tube lines were crippled, mostly due to the poor weather.
This morning, four lines were suspended - all maintained by Metronet:
· the whole East London line, due to multiple signal failures on the partly open track;
· the Circle line, clockwise only, due to an earlier signal failure;
· the Metropolitan line between Amersham and Rickmansworth due to a faulty train at Chorley Wood; and
· the Bakerloo line between Elephant & Castle and Paddington, due to a fire alert.
