A small atmospheric engine donated by the British Transport Commission, and erected by Mr Arthur Pyne, member of the Newcomen Society, in 1963. Its early history is not certain, but it was used by the Coventry Canal Company from 1821-1913 for pumping water into the canal at Hawkesbury Junction. It is fitted with a later form of condenser, but has the traditional timber rocking beam. The refurbished engine house now has a hydraulic mechanism and some descriptive material on display.
