SCOTRAIL has issued an update on its services ahead of strike action starting this weekend.

ScotRail has confirmed that its services will operate as normal when members of the RMT trade union and the train drivers' union, ASLEF, take part in industrial action. 

Members of RMT at a number of train operating companies across the UK plan to strike on Saturday, July 29.

ASLEF members plan to withdraw from non-contractual overtime from Monday, July 31 until Saturday, August 5. 

The strikes are a result of a dispute between the trade unions and a number of companies across the UK but it does not involve any ScotRail staff.

A small number of ScotRail services to Carlisle from Glasgow Central and Dumfries will be affected by the RMT strikes due to train dispatching being carried out by other operators in Carlisle. 

Phil Campbell, ScotRail head of customer operations, said: "The dispute between the trade unions and other train operators does not involve any ScotRail staff, which means we’ll be able to run our services as normal during the latest industrial action. 

"A small number of ScotRail services to and from Carlisle will see some disruption as a result of the planned RMT strike action, so customers travelling on this route should check their train times before leaving for the station.  

"We’d also encourage anyone travelling to plan their journey in advance, as we’re expecting our trains to be busier than normal due to customers of other operators travelling with ScotRail."
