Commuters were hit by rush-hour chaos after a signal failure caused major delays on the Central Line, while the Jubilee Line was part suspended after a customer was trapped between a train and the platform.

There is currently no service between Stratford and North Greenwich, and minor delays on the rest of the line after a commuter fell into the gap between a Tube train and platform and her leg was trapped at Canning Town station.

A spokesperson for Transport for London (TfL) said staff immediately stopped services to attempt to free the woman's foot, but had to get a jack to lift the entire Tube train so it could be removed. London Ambulance Service said the woman was treated at the scene and did not require hospital treatment.

Canning Town station has now re-opened.

The route was also temporarily suspended between Stanmore and Waterloo while engineers raced to fix a signal failure at Baker Street.

Crowd control measures were put in place at Waterloo and Canada Water stations, as commuters crowded on to station platforms.

There were severe delays on the line between Epping and Ealing Broadway, and on the branch to West Ruislip, due to an earlier signal failure at East Acton.

Authorities said that signal problems began at 7am and have now been resolved, but there are still delays as services return to normal.

Frustrated commuters tweeted pictures of crowded stations, and vented their anger.

Transport for London said on its website tickets will be accepted on the local buses, Chiltern Railways and Abellio Greater Anglia train services. At 8.50am, the Central Line tweeted that delays were now "minor".
