Firefighters were called to Maidenhead train station in the early hours of this morning to fill up a steam train which had run out of water.
The Brittania, which was on platform four, had been diverted from its normal journey from Cardiff to Southall because of rail works.
The diversion meant the train had run out of water and had to make an unexpected stop-off at the train station which is not normally part of its route.
Maidenhead fire service sent an engine at 2.30am to deliver the 1,500 gallons of water as a paid-for service.
Fireman of three and a half years, Michael Lovegrove, from High Wycombe, said he has never attended anything like this before.
He said: "It was a very strange call. I have not heard of it happening before and neither had any of our team. It was quite interesting though."
The cost of the service is not yet known.
