Train passengers will have to contend with a third day of strike action in September after another union announced it is to get in on the action.
In what has been dubbed the "summer of discontent", transport unions are in a row over pay, jobs and conditions with rail route operators and the UK's train infrastructure body Network Rail.
Two dates for walkouts in September had already been announced but a third has been added after Rail, Maritime and Transport union (RMT) confirmed it has agreed new dates for industrial action.
