More train strikes have been announced for this summer in the worsening dispute over jobs, pay and conditions.
It comes after thousands of people's journeys were disrupted due to mass walkouts last month. At the time, the RMT union said Network Rail plans to cut up to 2,500 jobs as part of a £2bn reduction in spending, with proposed job cuts including workers who maintain tracks, signals and overhead lines.
Earlier this week further action was agreed, and more dates have now been issued. Union leaders made the announcement after rejecting a new offer from Network Rail which they described as "paltry".
