A two-day subway strike that delayed millions of Londoners' journeys into work ended Thursday evening as the two sides agreed to restart talks.
Nine of 11 subway lines were fully or partly suspended because of the walkout by members of the Rail, Maritime and Transport Union over pay, disciplinary issues and job losses.
Transport for London, which manages London's public transport, said in a statement that the two sides would hold face-to-face discussions as soon as possible.
"It is a certainty that there has never been such a badly supported strike by the RMT and its members," said Mayor Boris Johnson. "The RMT have failed to produce the kind of mass disruption that they wanted and Londoners have got to work one way or another."
The union rejected Johnson's comments, saying support for the walkout was "solid."
