The Northern Belle - which was once part of the famous Orient Express group - leaves Sheffield on Thursday (May 12) at 7.35am heading to Bath.
A Northern Belle spokesman said: “We understand that people want to see the train and take photographs.
“However, safety must come first. So we ask them to show consideration both to our passengers and other rail users.”
Passengers heading to Bath, who have splashed out £370 each for a ticket, will board via a red carpet before being treated to a welcome glass of champagne followed by a three-course brunch and a five-course dinner accompanied by wine.
The Northern Belle spokesman said: “Bath, with its historic Roman baths, is one of our most popular destinations and this promises to be a wonderful day out. But we have very few tickets left so anybody wishing to go along had better be quick.”
The train is scheduled to arrive back at Sheffield station at 9.10pm that evening.
