hot 1896 – 1905 The Final Changes
Picture Of Engine Used Engine Onlyp1
In 1896 the No.1 engine (Boulton and Watt) suffered a major failure. With the No.2 engine now derelict, this caused a problem in keeping the canal open, and GWR were forced to do something about it as they had legal obligations to maintain the waterway. As a temporary measure, a railway locomotive was installed on blocks at the canal side adjacent to the pumping station with its driving wheels connected to a centrifugal pump. This was used to maintain the canal in water whilst the pumping station was overhauled. The Boulton and Watt engine was restored and the two Cornish boilers in the side boiler house were replaced with a new Lancashire boiler.
In 1905, the Sims engine was rebuilt with a new 1.07 m (42 inch) bore cylinder designed and manufactured in the GWR works at Swindon and the engine was reassembled as a conventional Cornish Cycle engine. At the same time, the three remaining Cornish boilers in the main boiler house were replaced by a second Lancashire boiler.
cold Introduction
The first design of the Kennet & Avon canal by the distinguished Scottish civil engineer, John Rennie, called for a 4.5 km (2.5 mile) tunnel between the Wiltshire villages of Crofton and Burbage but, in those days, tunnelling was a very expensive and uncertain process and a cheaper alternative was sought…….
cold The Original Installation
The first engine installed in the Engine House at Crofton was a second hand Boulton and Watt, purchased in 1802 from the West India Dock Company. This engine had a 90 cm (36 inch) diameter steam piston and a 2.5 m (8 foot) stroke. It had a wooden beam and worked a 66 cm (26 inch) diameter lift pump. It arrived at Crofton in 1807, and was at work by 1809……..
cold 1905 – 1968
Both engines were in regular service until 1952, and the 1812 Boulton and Watt continued to be used spasmodically until 1959, when, due to deterioration, the top 11 m (36 feet) of the chimney were removed making it impossible to fire the boilers as there was not enough draught……..
cold Restoration
On 14th April 1968, Crofton Pumping Station was purchased by the Kennet and Avon Canal Trust from British Waterways for £75 with the objective of restoring it to full working order. An appeal for funds was launched and a team of volunteers, including several qualified engineers began planning the work to restore the building, boilers and engines………
