ANTI-TERROR bollards have been put up at the entrance to Buchanan Street Subway station as part of a security review.
Bosses at Strathclyde Partnership for Transport (SPT) say they are there to stop vehicles being driven into the station, a tactic adopted by the terrorists who attacked Glasgow Airport in 2007.
SPT's head of security, Donnie MacLeod said: "The installation of crash bollards outside the entrances to Subway stations is part of our ongoing programme of security enhancements.
"It is not in response to any increased threat to the Subway, indeed the UK's Threat Level was lowered by the Government in July.
"That said, we would always ask passengers to remain vigilant and report anything suspicious to SPT staff."
The £271,000 contract to supply and install the crash bollards outside the entrances of SPT Subway stations was approved in October last year.
Luddon Construction won the contract after a competitive tender process.
The move comes after the terrorist atrocities of June 2007 when a blazing car was driven at the main terminal building of Glasgow Airport.
Eyewitnesses described the Jeep Cherokee being driven at speed towards the building with flames coming from underneath.
The jeep was stopped from entering the main terminal building by security bollards, preventing possible mass casualties.
Bilal Abdulla was jailed for 32 years last December for his part in the car bomb attack and his involvement in another plot in London's West End in June 2007.
Accomplice Kafeel Ahmed, died from his burns four weeks after the airport attack.
In June this year the Scottish Government announced that the number of counter-terrorist officers in Scotland was to be increased by almost 50% An extra £1.75million will be spent this year increasing numbers from 53 to 166, spread across all eight Scottish forces.
The extra funding will improve the tracking and pursuit of suspected terrorists, and increase community liaison work to address potentially violent extremism. The new posts include security advisers, financial investigators, intelligence assessors and analysts.
Announcing the funding, Justice Secretary Kenny MacAskill said: "The Glasgow Airport attack of two years ago showed that Scotland is not immune from that threat, and that is why we all need to work together to reduce the possibility of another terrorist attack in this country."
