Steam enthusiasts have been warned to stay away from the tracks as the world famous Flying Scotsman arrives in Norwich.

The locomotive is due in Norwich at approximately 7pm on Wednesday after departing Ely at around 5.30pm and steaming across the Fens.

And on Saturday it will depart Norwich at approximately 8am for Ipswich before retracing the outward route. In the afternoon the Flying Scotsman will depart Norwich for London at approximately 2pm.

Thousands of people are expected to try to see it and take photographs as it travels down the main line – but this has prompted fears of trespassers getting on to the tracks after serious incidents last year.

Special viewing areas have been set up at Norwich station, but Greater Anglia, which operates the station, has said these will be for a small number of people, on a first come first served basis.

People looking to see the locomotive elsewhere are being told by Network Rail and the British Transport Police to stay off the tracks and the railway boundary.

Inspector Stephen Webster, from British Transport Police, said: 'I hope that those wanting to see this iconic train have a fantastic day.

'I will have extra British Transport Police patrols along the route and would like to remind people not to trespass on the railway as it is extremely dangerous and is also a criminal offence.

'This includes standing on railway crossings and anywhere within the boundary fencing and I have instructed patrols to deal positively with any persons who break the law.'

Drone operators are also reminded hat flying within 50m of the railway is an offence and people have been warned against using selfie sticks due to the presence of overhead electricity cables.
