Steam Elephant
Design and development
By 1815 the success of Puffing Billy at neighbouring Wylam had encouraged other Tyneside collieries to commission steam locomotives. The Wallsend Colliery viewer John Buddle worked with the engineer William Chapman on a locomotive for the Wallsend Waggonway. The engine was built by Hawks of Gateshead — one of the first commercial locomotive orders placed with an outside engineering firm rather than constructed in a colliery's own workshops.
Steam Elephant adopted a different mechanical layout from the Hedley engines: a vertical boiler with twin vertical cylinders set into the boiler top, driving the rear axle through cross-beams and gear-coupling. The design avoided the long horizontal grasshopper beams of Puffing Billy in favour of a more compact engine.
Service and withdrawals
The locomotive entered service in 1815 and worked the Wallsend wagonway hauling coal. Steam Elephant was sufficiently successful to remain in service for several years, but was eventually superseded by more powerful engines as the wagonway was modernised. The original engine has not survived.
The locomotive was effectively forgotten for over a century until rediscovered in early 19th-century watercolours showing it at work. A working full-size replica was built between 2001 and 2002 to coincide with the bicentenary of locomotive development, and now operates at the Beamish Museum alongside other early-locomotive replicas.
Identification features
Distinctive vertical-boiler arrangement with twin vertical cylinders mounted within the boiler top, a tall chimney, and gear-coupled drive to the rear axle. A heavy four-wheel chassis with no leading or trailing wheels (0-4-0). The replica at Beamish is finished in dark green with red wheel centres.
