Reward offered over Angus train derailment
The rail industry has offered a £25,000 reward for information leading to the arrest of those responsible for a train derailment in Angus.
CrossCountry Trains' 08:04 service between Edinburgh and Aberdeen came off the rails at Inverkeilor on 4 November.
British Transport Police (BTP) said an obstruction appeared to have been deliberately placed on the tracks.
The reward is being offered by train operators CrossCountry Trains, ScotRail and East Coast.
There were 36 passengers on board the train, which was travelling at 76mph, when it came off the tracks at about 09:45.
None of the passengers were hurt, but the 49-year-old driver suffered a minor head knock and was treated by ambulance crews.
Det Insp Kevin McCormack, of BTP, renewed an appeal for anyone with information to get in touch.
He said: "It is hoped that by offering such a substantial reward someone will come forward with information that can help identify those believed to be responsible for such an irresponsible act."
David Simpson, Network Rail route managing director for Scotland, said: "This incident could have caused a very serious accident on the railway and put lives at risk.
"We are determined to do everything we can to support the police in their investigation and would encourage anyone with information about this stupid and reckless crime to get in touch immediately."
Andy Cooper, CrossCountry's managing director, added: "We are shocked that someone may have intentionally set out to injure our customers and staff and utterly condemn this criminal act.
"We urge anyone with information about this incident to contact BTP immediately."
Transport Police officers are continuing their investigation into the incident, alongside officers from Tayside Police.
An incident vehicle remains at the scene in Angus and additional high-profile patrols are continuing in the area.
