Police are warning of the dangers of trespassing on railway lines after tourists were spotted taking selfies on the viaduct which features in the Harry Potter films.
A couple with a young child were seen running on the railway line near the Glenfinnan viaduct in the Highlands while two men were also spotted on the track taking photographs.
The viaduct is on the route of the Jacobite Steam Train and also featured in several Harry Potter films when the Hogwarts Express crossed over it.
British Transport Police (BTP) said it has recently been made aware of a number of incidents where people have been seen on the railway line trying to view or photograph trains as they pass over the iconic structure, or walking on the West Highland Line towards Mallaig.
On one occasion a group of hillwalkers appeared to be wandering casually on the line between Glenfinnan and Arisaig.
BTP constable Nicky Ritchie said: “We know that visitors, many of them foreign, want to enjoy this incredibly scenic area and are keen to see and capture the trains, particularly steam trains, crossing what is without doubt a magnificent structure.
“However, they have to realise that they need to do it safely and without breaking the law.
“The proprietors of the Glenfinnan station visitor centre are also assisting us by making sure visitors are aware of the need to stay off the tracks.”
