Train drivers are to resume their strikes next month in the long-running dispute over pay.
Following the death of Queen Elizabeth II on September 8, the RMT, ASLEF and TSSA unions announced they had called off their strike action on September 15, 17, 26 and 27.
But the PA news agency now reports drivers at 12 train operators will walk out on October 1 and 5, affecting travel to and from the Conservative party conference in Birmingham.
