Wednesday is the day to see the Flying Scotsman steaming into Chester.
The iconic locomotive will whistle through the city on its route from Crewe to North Wales on June 15.
For safety reasons specific times for when the train is passing by are being kept under wraps.
Estimates suggest it could be at Chester Railway Station some time in the early afternoon, between noon and 2pm.
Operator Steam Dreams has advised those wanting to come out and watch should use bridges or ‘other suitable, safe places’.
A Steam Dreams statement said: “We respectfully asks that all people who wish to see Flying Scotsman do so from a permitted location and do not trespass on the railway.
“While we understand interest will be extremely high, we urge those wishing to view it on its tour dates do so from a safe vantage point.
“It is vital that spectators do not venture onto the railway, particularly when it is on the mainline as a full timetable of regular services will be running.
“Trespass is illegal and includes standing within the boundaries of the railway at a foot crossing when a train is approaching.”
The Scotsman’s appearance in Chester forms the opening day of The Emerald Isle Explorer trip to and from Ireland from London.
It holds the record for the first steam locomotive to officially clock 100mph and has been restored to its former glory in recent years.
Network Rail said ‘a huge number of trespassers’ keen to get a look at the Scotsman risked their lives by straying on to rail tracks earlier this year, which is why the precise timings of future journeys have not been revealed.
Network Rail managing director Phil Hufton said: “I cannot stress enough how dangerous it is to go onto the railway without any formal training and without permission, as well as being illegal.”
All tickets on board the trip have been sold.
Chief inspector David Oram from the British Transport Police said: “We understand people are excited about seeing the Flying Scotsman’s return and want them to have a great day out.”
