LONDON (Agencies): Rail passengers will face more disruption in December and January across Britain after the RMT union announced a fresh series of 48-hour strikes.
Thousands of members of the RMT working for Network Rail and 14 train operating companies will strike on 13-14 and 16-17 December, causing disruption in the run-up to Christmas. There will be a further two strikes on 3-4 and 6-7 January.
The strike includes crucial signalling staff, whose absence is likely to mean only a minority of services run on main lines while smaller lines have no trains at all.
Warning of more strikes came on Tuesday when the union accused rail bosses of reneging on a promise to submit a written offer at the end of two weeks of talks.
It ended hopes of a breakthrough in the long-running dispute over pay and working conditions, after a series of strikes scheduled for early November were called off at the 11th hour.
A separate strike by train drivers in the Aslef union will also halt many services this Saturday 26 November.
