Several thousand tickets have been sold for Christmas trips on the Severn Valley Railway despite three quarters of the line being closed by flooding.
Torrential rain in the summer caused the damage to the line
More than £2.6m damage was caused to the 16-mile (26km) line between Bridgnorth, Shropshire, and Kidderminster, Worcs, in the floods.
But officials say more than 5,000 tickets have so far been sold for their Santa Special trips in December.
The trains will run only between Kidderminster and Bewdley.
It is expected that most of the line open will reopen early next year.
The railway said many smaller jobs had been completed and it was aiming to have the whole line open by about March.
The line was damaged in 40 places by heavy rain in June.
Last month, officials said the appeal to raise money for repairs had reached £415,000 from public donations.
