The Elizabeth line is facing delays in a fresh blow for commuters, after a points failure at Slough has seen trains affected between Paddington, Reading and Heathrow airport.
It was one of the only Underground lines that was not participating in the ongoing strike action, which has the majority of the Tube network either suspended or heavily disrupted due to the RMT strike.
London Underground lines like Circle and Waterloo & City lines are fully suspended, while the District, Hammersmith & City, Northern and Victoria lines are experiencing severe delays, according to the TfL website. Parts of the Bakerloo, Central, Metropolitan and Piccadilly lines are also suspended. The Jubilee line is running with minor delays.
The strikes are now underway after talks failed to resolve a dispute over the working week, London Underground has said.
Members of the Rail, Maritime and Transport union (RMT) began a walkout after midnight on Tuesday and will do so again on Thursday, threatening huge disruption to travel in the capital.
TfL has warned the whole Tube network will be affected, with many lines running a reduced service.
The industrial action is in response to issues including a new four-day week, which the union has said its members do not agree with.
