Train collisions are relatively rare in Britain.
In September 2023, several people were injured after two trains collided at Aviemore railway station in the Highlands of Scotland.
The crash happened on the Strathspey Railway, a heritage railway run separately from mass-transit public services, and involved a stationary carriage and atrain in the station.
One of the trains involved was the record-breaking, century-old Flying Scotsman, the first steam train to reach over 100 miles an hour (161km), the National Railway Museum said.
In August 2020, an early morning service from Aberdeen to Glasgow came off the tracks, killing three people near the town of Stonehaven, northeast Scotland, after a landslip caused by heavy rain.
The driver of the train, a conductor and a passenger died and six other people were injured.
Network Rail – an arm of the UK Department for Transport – pleaded guilty in 2023 to safety failings at a court hearing and the public body was fined £6.7 million ($15.4 million).
