The team behind the heritage train which runs from Cheltenham Racecourse and Winchcombe, Toddington and Laverton has picked up the outstanding contribution to railway preservation prize at the Heritage Railway Association Awards.
It comes after the team has reconstructed lines damaged in landslips and used its imagination to continue services while doing so.
They will be presented with their award at a ceremony in London.
It was highly commended for its presentation of Winchcombe Station in the Restoration Award.
Malcolm Temple, chairman of the GWR said: "This could not have been a better Christmas present for the railway after such a struggle to overcome the serious embankment collapse problems we have gone through.
"Not only have we managed to raise over £1 million to pay for restoration of the collapsed embankments at Gotherington and then just north of Winchcombe station but the works have been completed to the highest possible standards, on time and under budget."
The railway reopened the newly rebuilt link over the most recent collapse at Winchcombe, on October 30.
