SCOTRAIL has said that train services to and from Glasgow Queen Street are "returning to normal" following earlier disruption. 

The train operator tweeted on Sunday afternoon that a "trespasser on the railway" was affecting all services to and from the station. 

It has since said: "Train services running to and from this station are returning to normal but some services will still be cancelled, delayed or revised."

When one social media user queried how long this would be for, ScotRail replied: “We will share any updates as we receive them.”

It also confirmed that it was affecting services on both the lower and upper levels.
