Central Line commuters faced a disrupted journey this morning after a signal failure caused severe delays throughout the line.
The incident, which occurred at Leyton at around 7:30am, caused knock-on problems as far as Epping, Transport for London said, with minor delays on the entire line.
TfL said it was unable to give an estimate for when the problem would be resolved. Tickets are being accepted on local buses, Abellio Greater Anglia trains and TfL Rail.
The Metropolitan Line was also struggling after a signal failure at Finchley Road caused minor delays between Harrow-on-the-Hill and Aldgate.
Commuters were suitably unimpressed.
