The crash happened at Aviemore Railway Station, in the Cairngorms, northern Scotland, at 7.10pm on Friday.

The National Railway Museum confirmed the steam locomotive had been involved in what it described as a "shunting incident".

"We will provide further information once more details are known," the museum said.

Carriages for the Royal Scotsman - a luxury sleeper train which travels on rail tracks around the Scottish Highlands - were also involved in the collision.

A spokesperson for Belmond, which runs the Royal Scotsman, said the "minor" collision took place when the Flying Scotsman was being shunted into place to be coupled with the Royal Scotsman train carriages.

"Thankfully, there were no major injuries," a spokesperson said

"All passengers have been transferred to a hotel, where our team is on standby to offer support and to assist with our guests' onward travel arrangements."

A Police Scotland spokesperson said two people were taken to Raigmore Hospital following the crash, but their injuries were not believed to be serious.

"A number of other passengers are being treated at the scene and enquiries are ongoing," the force said.

Three people had also been treated at the scene, but did not require hospital treatment, according to the Scottish Fire and Rescue Service (SFRS).

"Three appliances remain at the scene," a spokesperson for the service said.

The crash happened on Strathspey Railway, a heritage line between the nearby towns of Aviemore and Broomhill.

Scottish Greens transport spokesperson Mark Ruskell MSP said: "It is too early to know what has caused this incident, but clearly a full investigation will have to take place.

"We are thinking of all those involved at this challenging time and thanks all those who have taken part in the emergency response."

A spokesman for Network Rail said: "It's on a heritage railway line, it's not our infrastructure. The main line is shut while emergency services respond.

"We are saying to passengers to check before travelling."

Flying Scotsman - the steam locomotive which made history in 1934 by becoming the first to officially reach 100mph - was scheduled to be running trips this weekend.

The locomotive, built in Doncaster in 1923, is due to return to the south Yorkshire city on Monday as part of its 100th anniversary celebrations.
