Disruption will continue on Britain's railways on Friday as a dispute over jobs, pay and conditions remains deadlocked.
Members of the Rail, Maritime and Transport union (RMT) at Network Rail and 13 train operators went on strike on Tuesday and Thursday, with a third walkout planned on Saturday.
Travel chaos will continue on Friday, with only 60% of trains running, mainly because of a delay to the start of services as signallers and control room staff will not turn up for overnight shifts.
