In November 2008, a rare opportunity arose to manufacture two genuine steam locomotives for a client. The project was to build two models of the West Australian Government Railway “W” Class locomotives in twelve inch gauge (305mm).
Built to approximately one third of the original size, the locomotives were fully detailed and steam driven, the work including the boilers, cylinders and valve gear and chassis with matching tenders. The original locomotives were built in 1951, but the design of the replicas was updated to modern principles wherever practical.
With the locomotives and tenders weighing 3.5 tonnes each, they presented unique design and construction challenges. Working from detailed 3D CAD models and drawings, the manufacturing was done using modern CNC machining methods for both mechanical parts and the casting patterns. Locomotive-type boilers as well as steam control valves and accessories were manufactured to AS1228-2006 standards.
Together with dedicated engineers, knowledgeable steam enthusiasts and Kentin Engineering’s skilled staff, the end result is acknowledged to be superb and a representation of the quality workmanship offered by us.
A special thanks to all staff and others for a job well done.
