The train drivers Union Aslef has reached a deal with Southern Rail potentially putting and end to some of the strikes that have plagued the rail operator.
Aslef and the RMT unions have been striking over changes to the roles of guards, on which members will have to vote.
Details of the agreement have not been released and Southern’s disputes with the RMT continue.
Aslef general secretary Mick Whelan said: “This is a significant step forward in addressing the safety concerns of Aslef members on Southern Rail”.
“Aslef has never been against changes to working methods.
“Rather, we believe any changes should be negotiated through agreed procedures.
“I am confident this deal can provide a safer and appropriately staffed railway for passengers on Southern Rail and I will be recommending it to our members.”
Yhe Chief Operating Officer of Govia Thameslink, who own Southern Rail, said: the aim was always to reach an agreement with the unions.
“We’re delighted to have secured a deal today with Aslef to end their dispute.
“It’s good news for passengers, the regional economy and staff.
“After the misery and disruption to people’s work and family lives, we are pleased we can start to move forward and deliver a better railway for the travelling public.”
Separate strike action by the RMT union is set to continue.
