A MAN is in a critical condition after an incident on the subway line in the city's West End.

The man, whose age is unknown, was taken to hospital following the incident at Kelvinbridge yesterday afternoon.

Glasgow subway was forced to close down the outer and inner circles of the underground service after they received a report that the man was on the tracks. 

We told yesterday that the man could be heard shouting help.

An eyewitness took to Twitter and said: "Was at a station - Kelvinbridge I think when the girls opposite me freaked out and the train coming other way came to a sudden stop.

"The girls think they heard someone shout help and there were people kneeling on the platform looking down at the tracks through the train."

British Transport Police, however, said they are not treating the incident as suspicious. 

A spokesman for the force added: "Officers were called to Kelvinbridge station at 15.52 pm on Thursday, November 7 following reports of a casualty on the tracks.

"Paramedics also attended and a man was taken to hospital where he remains in a critical but stable condition.

"The incident is not being treated as suspicious."

We reported last month that Christopher McCarrol was left with devastating injuries after being struck by a train at the Bridge Street Station on October 3 with his guide dog Inca.

The 32-year-old was left with life-changing injuries.
