Erected in 1978, this device fills a steam locomotive's tender tank with fresh water. In a steam locomotive, a coal fire heats tremendous amounts of water to produce the steam that powers the train. The tender tank in Conway Scenic Railroad's steam locomotive No. 7470 holds 6,600 gallons of water and is topped off at this facility or a similar one inside the roundhouse at least twice a day. The metal spout above was salvaged from a wooden water tank that once served the Maine Central Railroad at North Belgrade, Maine.
