Leaders of the biggest rail workers' union have held a "productive" meeting with Liverpool's Metro Mayor in a bid to resolve a dispute over driver-only trains.
The meeting between Steve Rotheram came a day after the latest 24-hour strike by members of the Rail, Maritime and Transport union (RMT).
RMT general secretary Mick Cash said: "We have had a productive meeting today and there was a full and frank exchange of views and information.
"Both sides agreed to continue the dialogue and we will reconvene within the next six weeks."
