The train strike called off over the bank holiday weekend is back ON, with two walkouts now planned by Network Rail staff.

Members of the Rail, Maritime and Transport (RMT) union will strike for 24 hours from 5pm on June 4 and for 48 hours from the same time on June 9.

The workers, including signallers and maintenance staff, will also ban overtime from June 6-12.

The action comes after Network Rail staff rejected a new pay offer.

NR had originally offered a four-year deal - £500 this year followed by three years of increases in line with RPI inflation.

The new offer was for two years - a one per cent rise this year and around 1.4 per cent next year, with no compulsory redundancies for the duration of the agreement.

RMT general secretary Mick Cash said: "Our representatives have today rejected the pay package offered by Network Rail and, in the absence of any further movement from the company, that has left us with no option but to move to a rolling programme of industrial action.

"We have a massive mandate for action which shows the anger of safety-critical staff across the rail network at attacks on their standards of living and the blunt truth is that this dispute could be settled for a fraction of the money being handed out in senior manager bonuses and to the train operators for not running services. That is a ludicrous situation which should never have been allowed to have arisen.”

He added: “It is our members battling to keep Britain moving around the clock, often in appalling conditions, and they deserve a fair share from Network Rail for their incredible efforts.”

The Transport Salaried Staffs Association, which also suspended a Bank Holiday strike, said it will ballot its members on the new pay offer.

TSSA official Lorraine Ward said: "With the expected cuts in the public sector from the new Tory government, our members were as much concerned about job security as they were about pay.

"This offer means there will be no compulsory redundancies at NR for at least the next two years. Given the current climate, we think this is a major advance."

The result of the ballot will be announced on June 13.
