SOUTH Western Railway workers are set to strike for 27 days in December.
Members of the National Union of Rail, Maritime and Transport Workers (RMT) will begin the walk outs on Monday as part of a long running dispute with the franchise over the future of guard roles.
The strikes will be staged over 27 days next month in a move that could cause travel chaos over the Christmas period.
They are planned from:
- From 12.01am on Monday, December 2 until 11.59 on Wednesday, December 11
- From 12.01am on Friday, December 13 until 11.59pm on Tuesday, December 24 (Christmas Eve)
- From 12.01am on Friday, December 27 until 11.59pm on January 1, 2020.
