Railway workers will walkout across the country on 15th and 17th September in a fight over jobs, pay and working conditions.
Over 40,000 RMT members from Network Rail and 14 train operating companies will take to picket lines, effectively shutting down the railway network.
In separate disputes, Hull Trains and Arriva Rail London will also be taking one day of strike action on the 15th of September.
Negotiations between the union and rail industry have been ongoing but there has been no breakthrough or new offers from either Network Rail or the train operating companies in the national rail dispute.
RMT general secretary Mick Lynch said:
“Our members have no choice but to continue this strike action.
“Network Rail and the train operating companies have shown little interest this past few weeks in offering our members anything new in order for us to be able to come to a negotiated settlement.
“Grant Shapps continues his dereliction of duty by staying in his bunker and shackling the rail industry from making a deal with us.
“We will continue to negotiate in good faith, but the employers and government need to understand our industrial campaign will continue for as long as it takes.”
RMT issues response to Liz Truss being announced as the new Prime Minister.
RMT general secretary Mick Lynch said: “Liz Truss should act in the national interest and play a positive role in helping to settle the rail dispute.
“This means investment in the railway infrastructure, unshackling Network Rail and the rail companies so we can come to a negotiated settlement on job security, pay and working conditions.
“This would be in the best interests of the travelling public, the rail industry and railway workers.”
