A BANK holiday rail strike which was set to cancel the "vast majority" of ScotRail and cross-Border train services has been called off.

The industrial action was poised to bring around 90 per cent of the rail network to a standstill on Monday and Tuesday next week.

But RMT and TSSA, the unions representing rail workers, have now urged their members to go to work as normal on both days after Network Rail tabled a revised pay offer.

Thousands of signallers, maintenance workers, station staff and white-collar transport industry employees were due stage a 24-hour walkout accompanied by an additional period of work-to-rule in the biggest disruption to the UK railways in more than 20 years.

Union bosses will meet with workplace representatives next week to discuss the new offer, before notifying their members.

They had previously rejected a four-year pay deal with a one-off bonus of £500 followed by three years of rises in line with inflation, amid fears that a guarantee of no compulsory redundancies only extended to the end of 2016.

The RMT said the dispute hinged on concerns over an attack on "safety critical jobs" as well as pay and conditions, which would jeopardise railway safety.

ScotRail confirmed that its services will run as normal on both days, with services on the East and West Coast Main Lines between Scotland and London also reinstated.

Anthony Smith, chief executive of the independent watchdog Transport Focus (formerly Passenger Focus), said: "Passengers will be relieved that the planned industrial action has been called off. "It is passengers who suffer most in the event of strikes.

"Many had already been inconvenienced and had to seek advice about their plans for the weekend."

However, with the threat of industrial action lifted some passengers using the West Coast Main Line will still face disruption from planned maintenance works over the Bank Holiday weekend.

Throughout Saturday, Sunday and Monday, improvement works near the Border and at Newton in South Lanarkshire mean that passengers will have to be transported between Carlisle, Glasgow and Edinburgh on replacement bus services.
