Aerial shots - The Flying Scotsman's inaugural run from London to York after a 10-year refit has been ground to a halt by trespassers with Network Rail having to close the East Coast Mainline

CLEAN: Shows aerial shots zoom into The Flying Scotsman Steam Locomotive without much steam travelling through countryside. The Flying Scotsman's inaugural run from London to York after a 10-year refit has been ground to a halt by trespassers. Passengers describe how the steam locomotive was brought to a "shuddering stop" by train enthusiasts taking photos on the tracks. Network Rail said it had to "stop all trains" on the East Coast Mainline - including the world famous steam locomotive - "because of a huge number of trespassers" keen to get a look at it on February 25, 2016 in London, England.
