More than 650 people have been told their trip on the Great Marquess is off
Train passengers who were to be among the first since the 1960s to travel between Kincardine and Alloa have been left disappointed by cancellations.
Operators of the two steam train trips have been told they cannot run this weekend because of extra freight heading to Longannet power station.
The excursions will now have to be put back to Spring.
Passengers have been using the Stirling to Alloa line since May, but only freight travelled on to Kincardine.
The passenger carriages, pulled by the steam locomotive Great Marquess, were due to depart on Saturday from either Linlithgow or Dalmeny.
They would then head over the Forth Bridge, along the Fife coast and round the Fife circle before heading to the new Kincardine-Alloa-Stirling section of line.
Operators are angry they were given news of the cancellation at such short notice and will have to postpone the trips until next year because of engineering works, lack of daylight to enjoy scenery and the availability of the Great Marquess.
Roger Haynes, from SRPS Railtours, said: "We've had to inform over 650 passengers that we'd had to call it off at just over a week's notice.
"It was the first chance for people from Scotland to travel over this newly rebuilt section of line - the whole route - so it's disappointed a lot of people.
"We had large numbers from Alloa, Tillicoultry, Clackmannan, and various points along the line, who'd booked to travel because they wanted to see the whole line.
"There are also a significant number who were travelling a long distance for the trips and had no doubt already booked travel and accommodation."
Mr Haynes added that it was also a significant blow to the Scottish Railway Preservation Society as the tours were organised by volunteers to raise money for the museum at Bo'ness, cash that they now had to refund.
