Southern Rail services will run as normal from next Tuesday after rail union Aslef announced it had called off a planned strike.
The industrial action, due to have taken place on Tuesday, Wednesday and Friday, has been cancelled due to fresh “intensive talks”.
The strikes now cannot go ahead, even if talks fail.
“Once strikes have been called off, we can’t put them back. We would have to look at other dates if the talks fail,” said an Aslef spokesperson.
The dispute centres on the role of guards on trains. Southern wants the train driver to open and close the doors, which unions claim could compromise safety and lead to job cuts.
Angie Doll, from Southern, said strikes were “wholly futile”.
“Due to the changes we’ve now fully rolled out, we’re now able to run more services on more routes serving more passengers and ultimately we’ll have fewer cancellations and delays.
“The RMT should now recognise that their industrial action is wholly futile. They should stop the strikes, get back round the table with us and move forward together with us, delivering a better railway for our passengers,” she added.
