Drainage engine used for clearing Pinchbeck Marsh. Engine house of red brick with hipped slate roof; cast-iron windows and doors, and a date stone of 1833. The chimney has been demolished to eaves level. Inside, the building is divided by a spine wall; to one side is a boiler, manufactured by Galloways Ltd and dated 1893. The adjacent beam engine is probably the original one with later alterations: there is no maker's plate, and it has a high pressure cylinder as well as the normal low pressure one. The flywheel drives, via reduction gears, a swop wheel. Well maintained and in a good state of preservation - The Internal Drainage Board aims to keep this in very good condition, and consequently they spend a fair amount of money on it. {1}{2}{3}
