London commuters faced Tube delays after snowfall
London's commuters have faced delays on a number of Tube lines after the capital had several centimetres of snow overnight.
There were delays on the Circle, District, and Hammersmith & City lines because of the snow, Transport for London (TfL) said.
The Jubilee line had severe delays and was suspended between Stanmore and Waterloo, because of a faulty train.
TfL said "heavier than expected snowfall" led to a train stalling.
Passengers on the Metropolitan line faced severe delays because of a signal failure earlier at Rayners Lane.
London Underground chief operating officer Howard Collins said: "Throughout last night, TfL put its cold weather plans on the Tube, DLR, London Overground, buses and roads in place.
"The vast majority of services are running well this... with traffic flowing well on main roads.
"On the Tube, the vast majority of services have run well but there were defective trains on the Jubilee and District lines that caused disruption for some of our passengers, for which we apologise."
The capital's airports were not reporting any major delays.
A Heathrow Airport spokesman said: "A light fall of snow overnight was cleared by Heathrow's snow team with no disruption to the airport.
"A normal schedule is planned for Friday with no anticipated disruption."
