A seagull has reportedly been trapped overnight in the front carriage of a ScotRail train.

A commuter tweeted that the front coach of the 7.11am service between Leuchars and Edinburgh had been out of use due to the bird.

The train originally set off from Aberdeen at 5.46am.

Believed to be a seagull, the bird "became trapped in the carriage and repeatedly crashed into the windows, leaving a trail of blood and debris".

Replying to Baktosch Gillan's tweet, a ScotRail social media manager said it was "one of the oddest events I've heard of in a while".

A ScotRail spokesman said: "We're very sorry for the lack of the capacity on this service.

"But we are pleased to confirm that the bird is alive and well."

Several other faults caused rush-hour disruption for rail commuters on Monday morning, particularly around the east coast and central belt.

Signalling problems at Drem led to replacement buses from North Berwick for passengers going to Edinburgh.

A similar fault at Edinburgh Park causing delays for the the Edinburgh to Glasgow via Falkirk and the Edinburgh to Dunblane services, with disruption expected until 11.30am.

There were also only three carriages for a number of rush hour services travelling between Edinburgh and Glasgow Queen Street earlier in the morning.
