A further two days of strike action hits ScotRail services

The dispute centres on the introduction of additional driver-only operations

RMT union members working for ScotRail are taking part in a further two days of strike action.

A number of services on Saturday and Sunday have been cancelled or reduced, although ScotRail has claimed that 76% of routes will operate as normal.

The industrial action is over the union's concerns about trains operating without guards.

On driver-only-operation trains, the driver is asked to close the doors at stations, instead of a conductor.

ScotRail has said it would ensure a second member of staff was scheduled to be on board every train to assist the driver in emergencies.

However, the company has accepted there are occasions when a ticket examiner does not turn up for work that a train could run with only a driver and Scotrail has said it has union agreement for this.

The union believes the absence of a dedicated guard would make trains less safe.

ScotRail has predicted that this weekend's strike will not affect services to Troon, where the Open golf championship is being held.
