THE world’s most famous steam train the Flying Scotsman is due to pass through south Devon tomorrow as it marks its centenary year. 

The iconic locomotive will be will be travelling through Dawlish to Newton Abbot as part of a scenic trip from Bristol to Cornwall.

Celebrating its 100th birthday, the Flying Scotsman is one of the best-loved steam trains in the world. 

And tomorrow is a rare chance to see it in action. 

Exact timings of the journey are being kept under wraps to avoid over crowding at popular vantage points along the route. 

But it is due to depart Exeter St David’s at about 11.30am. 

The route will take the spectacular steam train down the banks of the Exe estuary, along the iconic coastal route from Dawlish Warren to Teignmouth before heading inland along some of the steepest climbs on the rail network. 

Tomorrow’s journey is one of a number of events organised to mark its centenary. 

Built in Doncaster in 1923, the locomotive was the first steam train to reach 100mph. 

Retired from British Railways in 1963 after covering more than two million miles, it is now owned by the National Railway Museum in York.
