water, per stroke, at a rate of 10.2 strokes a minute. When the Great Western Railway built its railway line through the area, it passed very close to the station and between it and the canal. Access between the canal side and the pumping station is now via a very low roofed tunnel. History The pumping station was built between 1807 and 1809 in time for the opening of the canal in 1810. The station was built to house two pumping engines, but only one, a bore engine bought second-hand from the West India Dock Company, was initially installed. In 1810 a second engine was ordered from Boulton and Watt. This engine, which started work in 1812, is the current number 1 engine, and has been the main engine throughout the steam-driven life of the station. In 1846 the original 1809 engine was replaced by a new engine supplied by Harvey and Co. and built as a double-acting Sims patent combined cylinder engine. However, this engine proved troublesome and eventually fell into disuse. In 1903 the 1846 engine was rebuilt as a simple single-acting engine and thus became the current number 2 engine. Both engines then continued in regular use until the 1950s, when the state of the chimney forced the removal of the top . The reduced height chimney was unable to provide sufficient draught for the boiler, and it proved cheaper to retire the steam engines and install electric pumps. In 1968 the pumping station was bought by the Kennet and Avon Canal Trust with restoration in mind. The building and both engines were restored, and the existing irreparable boiler replaced with another of the same type acquired second hand. Number 1 engine was first successfully steamed on 4 April 1970 and the pumping station was officially reopened on 21 August the same year by John Betjeman. Number 2 engine was first successfully steamed on 15 November 1971. The pumping station was designated as Grade I listed in 1985. Initially the problem of the shortened chimney was overcome by the use of an electric fan to improve draught, but between 1996 and 1997 the chimney was repaired and restored to its full original height of . In July 2009, the modern electric pumps at Crofton failed. While awaiting repair, British Waterways contacted the Kennet and Avon Canal Trust who put Crofton into steam. In 2012 the Boulton and
