Whether it’s the real-life Reptile House at London Zoo where a python first spoke to Harry, London’s Leadenhall Market which doubled as Diagon Alley, or the imaginary Platform 9¾ at Kings Cross station, if it featured in the Harry Potter films, you can bet it’s become a major tourist attraction.

But there’s one landmark for fans of the films that seems to be landing them into big trouble.

Police in the UK are warning Harry Potter fans against walking along the live railway track in the Scottish Highlands, where the Hogwarts Express can be seen chugging along on screen.

There has been an increase in the number of intrepid fans crossing the Glenfinnan Viaduct, which services the Jacobite steam train, and police warn they’re putting themselves in serious danger.

British Transport Police said it understood the fascination with the viaduct but “people do not have any magical powers so there is nothing to protect them from being injured or killed by a passing train”, the BBC reported.

Sgt Kevin Lawrence said: “Tourists from all over the world travel on the Jacobite steam train during the summer months to visit the famous Glenfinnan Viaduct.

“Alarmingly, visitors often get off the train at Glenfinnan and walk back along the line to take photographs. This is extremely dangerous.

“The scenic, rural area also attracts many bikers and other tourists also travelling by road to see the viaduct.”

He added: “Much as we love Harry Potter, I would like to remind everyone that we are mere Muggles, and if you trespass on the railway and are struck by a train, the consequences could be extremely serious and probably fatal.”

A rise in the popularity of the viaduct is partly behind a 16 per cent rise in railway trespassing offences in Scotland last year, police said.

And there have been a number of close calls. Five years ago, a steam train driver was forced to brake after seeing two women standing dangerously close to the train line, the BBC reported.

And in 2015, a couple and their child were seen running along the railway line.
