A freight train derailment caused major disruption for people travelling on the Dundee-Aberdeen line on Wednesday evening.
The train left the track as it was joining the main line at the south side of the Craiginches Yard, two miles south of Aberdeen.
The incident, which occurred at 4.50pm, affected the services of trains throughout the evening.
Buses were laid on for passengers travelling between Dundee and Aberdeen. Commuters at the stations of Arbroath and Montrose travelled to Stonehaven by train before boarding a bus to Aberdeen.
However, frustrated passengers at Dundee station were annoyed that there did not seem to be any clear direction for transport arrangements to destinations other than Aberdeen.
Gillian Bryan (72) and her husband Anthony boarded a train in Leeds at 3.05pm to visit family in Arbroath.
Their train was terminated in Dundee just before 8pm and they were unsure how they would get to their final destination.
”We are supposed to be picked up from Arbroath but this bus is only going to Aberdeen now,” she said. ”My family organised a taxi to pick us up from Arbroath station. I don’t think it’s been well handled.”
Norwegian businessman Einar Wathne was travelling north with a group of colleagues when they were forced to switch to buses in Dundee.
He said: ”We are coming from Inverkeithing and heading to Aberdeen. We are heading back to Norway on a morning flight.”
Student Alex Eakin said: ”I set off from Edinburgh at 6.10pm. It’s got to Dundee on time. I’m not feeling great but what can you do? There’s no point complaining.”
It is understood that only a driver was on board the freight train and he was unharmed in the accident.
A spokesman for Network Rail said: ”We are currently trying to establish what happened to the train, then we will look at how easily it can be righted and investigate any damage to the track.
”We apologise for the inconvenience and will do everything we can to resolve the problem as soon as possible.”
Network Rail later said trains were running on the route again with delays until the close of service.
Freightliner Heavy Haul, who operate the train, were unavailable for comment.
