Workers employed by three train operators are reported to be solid in their support of strike action as the dispute over driver-only trains rumbles on.
Rail, Maritime and Transport union (RMT) members at Arriva Rail North, Merseyrail, and Southern Rail have begun a 24-hour walkout, with another one planned for Monday.
The dispute is a long-running issue, with the union - which represents train guards - having been pitted against train operators for more than 16 months. The deadlock has seen numerous strikes, particularly on Southern Rail.
RMT members working on South Western Railway have also reportedly been balloted for industrial action, over the same issue.
Southern has said it plans to run most of its services despite the walkout, while services across Arriva Rail North and Merseyrail are reduced.
Mick Cash, the RMT’s general secretary, praised the unity amongst workers and defended the strikes as necessary because they were about putting “passenger safety before private profit.”
