Commuters faced lengthy queues at Glasgow Queen Street station during the first evening rush hour after repair works began.

ScotRail has said it will make changes to its services following the queues on Monday, which were caused by a peak train running late.

The Queen Street tunnel in Glasgow will be closed for five months, with trains diverted to either Queen Street low level or Glasgow Central Station.

The rail operator said the tunnel is being upgraded to allow faster, longer and more environmentally friendly trains to run between Edinburgh and Glasgow.

On Monday, pictures posted on social media showed lengthy queues around the station.

A ScotRail Alliance spokesperson said: "This was the first day of the project and, for the most part, we kept people moving throughout the day and into the evening peak.

"We have been reviewing the situation throughout the day and we will make a few tweaks to the queuing system ahead of tomorrow.

"This should make it that little bit easier for people to find their train and get to where they are going.

"We are really grateful for the patient way our customers are dealing with the changes to their journey."
