PASSENGERS on the Glasgow Subway suffered travel chaos after a man was struck by a train.

The entire network was forced to shut down as firefighters battled to free the man trapped under a train in the city centre.

He is thought to have walked into a tunnel at St Enoch station at around 1.30pm yesterday.

Transport chiefs were forced to suspend both circles in the wake of the incident and the station itself was cordoned off.

Commuters were advised to take buses instead and a limited shuttle service was running between Partick and Govan.

But the drama left commuters stranded, with some having parked their cars at subway stations on the other side of the city.

Firefighters used specialist equipment to free the victim but he was found to be suffering serious injuries.

He was rushed to Glasgow Royal Infirmary where he remained in hospital today with serious leg injuries, but they are not thought to be life-threatening.

British Transport Police said their investigations were continuing.

A spokeswoman for Strathclyde Partnership for Transport said today: "The service was never completely closed.

A shuttle service operated between Partick and Govan to provide the river crossing and full service resumed later on both circles."

Both subway routes were back up and running two hours after the incident.

SPT reopened the outer circle at 3.10pm, while the inner circle was restored around half an hour later.

St Enoch Station was reopened to passengers at around 4.30pm.

The incident happened a week after British Transport Police began patrols on the underground on a regular basis to improve security.

Two full-time officers have been assigned on a two-month trial.
