The world's most famous steam locomotive will stop at two Norfolk stations this week as part of its centenary celebrations. 

Passengers will ride behind the Flying Scotsman this Friday, June 23 on the Great Yarmouth Flyer.

It was originally scheduled for Saturday, June 24, but the date was moved due to weekend engineering work. 

The Flying Scotsman entered service in 1923 at Doncaster Works as the first locomotive of the newly-formed London and North Eastern Railway (LNER).

It was designed by Sir Nigel Gresley as part of the A1 class - the most powerful locos used by the LNER at that time.

The train will depart London King's Cross in the morning and it will pass through locations including Stevenage, Cambridge, Ely, Thetford and Wymondham.

It will then arrive at Norwich Station for 12 minutes in the early afternoon, where the train will reverse and be diesel-hauled to Great Yarmouth via Brundall and Acle.

It will then stop for a few hours in Great Yarmouth for passengers to explore the seaside town, while the Flying Scotsman is serviced and prepared for the return trip to London. 

To avoid overcrowding and trespassing, The Railway Touring Company does not publish journey times.

Greater Anglia has issued a safety warning ahead of the visit, with onlookers not permitted past the barriers at the railway stations in Norwich or Great Yarmouth.

In the city, Flying Scotsman fans are advised to stand on Riverside/Koblenz Avenue or the Carrow Road Bridge over the railway.

James Reeve, Greater Anglia’s area customer service manager, said: "Flying Scotsman will not be the only train running on our railways – there will be many other regular, scheduled services operating, so it is vital that rail fans stay in safe areas and don’t trespass on the line and put themselves and others at serious risk."
