Commuters are battling severe delays on the London Underground as a signal failure sparked chaos on three Tube lines.
A signal failure at Farringdon sparked severe delays on the Circle, Hammersmith & City and Metropolitan lines on Monday morning, Transport for London said.
Metropolitan line services were suspended between Baker Street and Aldgate on the Metropolitan line. Commuters also faced severe delays between Harrow on the Hill and Baker Street.
Meanwhile passengers on the Victoria and Piccadilly lines suffered minor delays. A faulty freight train caused disruption on the London Overground between Clapham Junction and Surrey Quays.
Most of the disruption was resolved by midday on Monday, with only the Piccadilly line suffering minor delays by lunchtime.
A second signal failure caused delays between Hatton Cross and Heathrow Terminal 4 on the Piccadilly line.
Commuters faced setbacks on the Victoria line while engineers dealt with a faulty train at King’s Cross.
TfL said there was a good service on all other lines while they were working to fix the issues.
A TfL spokesman told the Standard: “We apologise to any of our customers whose journeys were affected by the signal failure at Farringdon this morning.
“Engineers are working hard to repair the fault as quickly as possible. We aim to be back up and running as soon as possible.”
The chaos came as the Met Office issued dozens of weather and travel warnings ahead of widespread snow and ice expected across the UK – including in London and south east – although TfL stressed the disruption was not related.
A yellow warning has been issued in the capital from 2pm on Monday and is set to be upgraded to Amber from 2am on Wednesday amid fears of widespread travel disruption.
Flurries of snow fell in London on Monday morning following a bitterly cold weekend which saw a blast of Siberian air dubbed the ‘Beast from the East’ hit the UK.
