A total of 27 days of strike action will take place on South Western Railway next month, the RMT union has said.

The planned walkouts are due to begin on Monday 2 December as part of a long-running dispute over guards on trains, threatening travel chaos for commuters and Christmas shoppers.

RMT general secretary Mick Cash claims its members had been "left with no choice" - accusing the company of "dangling" a potential breakthrough deal in front of the union, and then failing to honour it for no reason.

He said: "At the last meeting we held with SWR, principles in agreements were made in good faith with the company's negotiating team and we now feel hugely let down again.

"I want to congratulate our members on their continued resolve in their fight for safety and the role of the guard on SWR.


"It is wholly down to the management side that the core issue of the safety critical competencies and the role of the guard has not been agreed."

In a statement announcing the strike dates, the RMT union said: "The company's unremitting failure to give assurances that their new operational model won't move to Driver Controlled Operation - with the role of the guard butchered completely - means the union has been left with no alternative but to call further industrial action."

Sky News has approached South Western Railway for a response.

RMT workers are due to go on strike:

From 12.01am on Monday 2 December until 11.59pm on Wednesday 11 December

From 12.01am on Friday 13 December until 11.59pm on Tuesday 24 December

From 12.01am on Friday 27 December until 11.59pm on 1 January

News of the industrial action came on the same day rail passengers were warned about engineering work on some of Britain's busiest lines over Christmas.

London Paddington will be closed from 24 to 27 December and a reduced timetable will be in place for four days afterwards so work can be carried out on the heavily delayed Crossrail project. Great Western Railway, Heathrow Express and TfL Rail services will all be affected as a result

Major works will also take place at London's King's Cross, including tunnel and structure work, drainage inspections and upgrading overhead line equipment.

Other engineering work means Southeastern high-speed and Eurostar trains will not stop at Ashford, Kent between Boxing Day and 29 December.

The majority will be done on Christmas Day and Boxing Day - when most of the rail network is traditionally shut down - but there will also be limited trains from the station during the morning of 27 December.

There are around 25% fewer engineers working during the period compared with 2018, meaning more lines and services will operate as normal.

In total, Network Rail is carrying out 386 projects over Christmas.

Its chief executive, Andrew Haines said: "Our passengers want and deserve a more reliable railway and that's why this Christmas we are out working on the track and behind the scenes to help make that happen.

"Significantly fewer people travel over the Christmas holidays, which is why we do so much work at this time of year.

"But we know some of our passengers will have important plans, so please check before you travel. We have plenty of people in our stations in the run up to and over the break who are on hand to help."
