Network Rail offers £10,000 over Glasgow signal damage
A £10,000 reward is being offered for information leading to the arrest of people behind a spate of vandalism to train signalling equipment in Glasgow.
Since 4 June, damage has been reported at Queens Park, Yoker, Nitshill and Jordanhill stations.
Network Rail offered the reward after British Transport Police (BTP) said the incidents may be linked.
Security is also being stepped up with extra staff, increased patrols and a helicopter to monitor the railway.
BTP said all of the incidents had caused "extensive disruption", with hundreds of trains across the greater Glasgow area being cancelled or running late.
The nature of the faults at each location and the timing of the incidents has led Network Rail and BTP to believe that they could be linked.
Both bodies also say they may "represent a deliberate attempt to disrupt rail services" across Glasgow.
Ch Insp David Marshall, of BTP, said: "Vandalism such as this is extremely disruptive. The public can be assured that BTP and the rail industry is taking this series of incidents extremely seriously and resources are being deployed to apprehend those responsible."
BTP and Network Rail said none of the incidents had compromised passenger safety as signalling equipment automatically goes to a red signal if faulty and all trains stop moving.
David Simpson, Network Rail route managing director for Scotland, said: "The incidents under investigation, while of no danger to the public, have caused significant levels of disruption and delays to thousands of passengers across the city over several days.
"Deliberate vandalism cannot be tolerated and we are working closely with BTP to investigate the incidents that have already occurred and to deploy resources to help prevent any further targeting of our network."
