Central line services are now running between Epping and Marble Arch, despite The tube strike.
The stations of Wanstead and Redbridge are closed.
Members of the Rail, Maritime and Transport union (RMT) are protesting at plans to close Tube ticket offices.
Full service on the network will resume at 9pm tonight, but the RMT is threatening another three-day strike from 9pm next Monday.
