Vandals have attacked two carriages at the world-famous Severn Valley Railway site at Kidderminster, forcing them off the tracks.
Staff at the Worcestershire site confirmed graffiti had been left on the train carriages, including one pulled by the historic Flying Scotsman locomotive.
One of the carriages had the name 'Banksy' spray painted on it, although it's not thought the secretive street artist was involved.
The carriages were targeted at some point between Christmas Eve and Boxing day.
They're now running shorter journeys for some train journeys and have removed the vandalised carriages.
The repair work is expected to last until mid February 2018.
An investigation is now underway.
We are extremely saddened by this turn of events, especially in the season of goodwill. But, in true Severn Valley Railway spirit, we will continue with smiles on our faces and ensure the much-loved and painstakingly-restored vehicles are returned to service as quickly as possible for our passengers to enjoy.
Thank you for your messages of support this morning. The vehicles are owned by our Charitable Trust who have an online donation facility if you would like to help us return these, and other beautiful vehicles to service as soon as possible
