A water crane is a device used for delivering a large volume of water into the tank or tender of a steam locomotive.[1][2][3] The device is also called a water column in the United States and Australia.[4] As a steam locomotive consumes large quantities of water, water cranes were a vital part of railway station equipment, often situated at the end of a platform, so that water could be refilled during a stop at the station.
