Harwin Harwin

Harwin is based on Lima locomotive works 2-6-2 design from the USA. The Wato engineering castings were imported from Australia a number of years ago, and construction was started by Bill Knox who had completed the chassis and cylinders. After Bill passed away the part completed locomotive moved to Nick and Graham Taylor who were friends of Bill. Harwin was completed in October 2016. Harwin is pictured at Willowbank Station in October 2016 on one of its first running sessions.
