Police have issued an urgent appeal after railway enthusiasts trespassed on tracks to catch a close glimpse of Flying Scotsman.

The incidents occurred on Sunday as the world famous steam locomotive travelled across the East Midlands.

Some 56 regular passenger trains were delayed as they were forced to travel slower than normal because of the track incursions.

British Transport Police (BTP) released a photograph of two people standing next to a 125mph line in Elford, and asked anyone who recognises them to come forward.

BTP chief inspector Gareth Davies said: “It is extremely disappointing that a small minority of rail enthusiasts put their lives in grave danger in an attempt to take photos of the Flying Scotsman.

“Quite frankly, they should know better and we are today sending a strong message that this will not be tolerated.

“We’re making a number of urgent inquiries to identify those who trespassed on the tracks. I would therefore ask anyone with information to get in touch.

“The railway is an extremely hazardous environment.

“Trespassing could result in serious injury or even death.

“In order to prevent further incidents, we’re stepping up our patrols when the Flying Scotsman is out on the rail network.

“Those caught trespassing or obstructing trains can expect to be prosecuted.”

A number of BTP resources were deployed on Thursday to deter trespassers as Flying Scotsman travelled between York and Edinburgh along the East Coast Main Line.
