Police have warned tourists visiting the iconic railway line made famous by the Harry Potter films that they may be putting themselves in danger.
British Transport Police (BTP) has released a warning ahead of the October half-term holidays to advise both locals and tourists of trespassing concerns.
The 21-arch Glenfinnan Viaduct, which is on the line of the Jacobite Steam Train, famously featured in the Harry Potter films as the route of the Hogwarts Express.
BTP says they have 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 Viaduct, or walking on the West Highland Line towards Mallaig.
During summer, train drivers and maintenance staff reported a couple with a young child running on the railway line in the vicinity of the viaduct.
Two men on the lines taking photographs and a group of hill walkers appearing to be wandering on the line between Glenfinnan and Arisaig were also reported.
Constable Nicky Ritchie of BTP is advising both local people and tourists to keep safe.
"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," he said.
“However, they have to realise that they need to do it safely and without breaking the law.
"We have been working closely with Network Rail to advise local people, sightseers and tourists about the dangers of trespassing and the possibility of disrupting the rail network.
“I’m grateful for the co-operation of West Coast Railways, who carry thousands of tourists to the area each year, who have now included advice on their website for anyone booking a trip on one their charter steam trains.
“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.”
Mark Henderson, senior community engagement manager for Network Rail, added: “Trespassing is extremely dangerous and can have tragic consequences for those involved.
“Trains travelling at speed take a long time to stop and anyone struck by one is likely to be killed or very badly injured.
“We work closely with BTP to educate the public on the dangers of misusing the railway and are committed to making sure people fully understand the risk they face when straying onto operational railway land.”
