Tourists determined to get a good view of a steam train made famous by the Harry Potter films are being warned to stay off the tracks at a beauty hotspot.
West Coast Railways' Jacobite train service runs through the Highlands from Fort William to Mallaig and passes over the renowned Glenfinnan Viaduct.
The viaduct - on the West Highland Line - had a starring role in a number of the boy wizard movies based on JK Rowling's books, and attracts thousands of excited Potterheads from around the world hoping to catch a glimpse of the "Hogwarts Express".
According to the National Trust for Scotland, Glenfinnan welcomes 600,000 visitors annually.
As the Jacobite's latest season gets underway, Network Rail Scotland is urging visitors to put safety first.
Neil Cook, route crime manager, said: "The Jacobite steam train's journey over Glenfinnan Viaduct is a magical sight but it's not worth risking your life for.
"Too often, we receive reports of dangerous behaviour, with people climbing fences, standing on the railway, or walking along the track to try to get closer.
"Trains can come from either direction, are quieter than people expect, and can't stop quickly.
"The Glenfinnan Viaduct Trail offers dedicated viewing spots and most importantly, keep people a safe distance from the railway.
"We insist everyone visiting uses those areas and helps keep themselves and others out of harm's way."

Trespassing on the railway is a criminal offence and applies to the tracks, the viaduct and surrounding railway land.
Anyone caught can be removed, issued a fine and prosecuted in court.
Chief Superintendent Lorna McEwan, from British Transport Police, said: "Stepping on the tracks is never worth the risk - it's illegal and puts lives in immediate danger.
"Every trespass incident not only risks serious injury or worse but also causes major disruption for passengers and freight across the network.
"We work closely with our partners at Network Rail to detect and deter trespass, as well as taking enforcement action for anyone who disregards the rules and places themselves or others in danger.
"Please follow the advice - stay off the tracks, follow the guidance, and enjoy the view safely."
