TRAIN services between Glasgow and Inverclyde will be disrupted tomorrow due to strike action by signalling staff.

Some trains will be withdrawn, while others will operate a reduced service in a row over staff promotion.

In Glasgow, Cathcart Circle services will not operate on Christmas Eve and services via Maxwell Park will have just one train per hour. Services via Queen's Park will operate three times an hour.

A spokeswoman for ScotRail said: "We apologise for any inconvenience. Everyone should check their journey before they set out, in particular noting their last train home."

Gourock services will also be hit, with trains reduced from three per hour to two. These will depart Gourock at six and 36 minutes past the hour and leave Glasgow Central at five and 35 minutes past the hour. Barrhead, Paisley Canal and Whifflet services will be cut from two to one per hour.

Services from Barrhead will depart at 27 minutes past the hour and leave Central at 57 minutes past the hour. Trains will depart Paisley Canal at 30 minutes past the hour and Glasgow Central at eight minutes past. Whifflet services will leave at 36 minutes past and depart Glasgow Central at 46 minutes past.

ScotRail said extra carriages will be added to trains where possible. There are no other changes to services to and from Argyle Street and Glasgow Central, other than the normal Christmas Eve run down.

Network Rail said it was "disappointed" that negotiations to avoid the strike with the RMT trade union had proved unsuccessful.

The dispute affects 32 staff based at the firm's west of Scotland signalling centre.
