Central Line track fault disrupts Tube service in London
Services on a section of the Central Line running through central London were suspended due to a faulty track, Transport for London (TfL) said.
The fault occurred at St Paul's station in the City at about 19:00 BST on Monday.
The line was suspended between Liverpool Street and White City and there were severe delays on the rest of the line.
Engineers worked into the night to fix the section of track.
In total 15 stations on the route - including key central London stations in the West End, and Bank, St Paul's and Liverpool Street in east London - were affected.
There were also problems on London Overground with services being suspended for more than four hours.
The disruption, between Canonbury and Stratford, began at 17:20 BST, before service was restored at 21:30 BST, but there were severe delays for another hour.
