The Railway welcomes 2 new engines this season, one for the ground level railway and one for the elevated railway.

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.

King Edward I

King Edward I
GWR 6000 Class 6024 King Edward I was built at GWR's Swindon Works in June 1930, for most of its working life it was allocated to Plymouth Laira MPD. Transferred to Old Oak Common MPD, London, in March 1959, and finally to Cardiff Canton TMD in 1962.
This 5" Gauge scale model model is relatively new, and worked very well when run earlier in the year. King Edward I is pictured on our railway in February 2017 just after steaming up for its turn of duty.
