Update: The HO Scale works train carriages now have a new home in Colorado, USA. The Bachmann 3-truck Shay has a new home in Great Britain.
Here are photos of the Britannia Creek Work Train in HO scale taken in 2004. The Britannia Creek work train consisted of a Bachmann 3-truck Shay and the HO scale Backwoods work train kit from Sierra West Scale Models. These cars were built over the 2003-2004 holiday period. It is fair to say these models are best as static displays as their weight and centre of gravity is not ideal for running.
This photo of the entire set is taken with a real life background.
Here are various elements of the Britannia Creek Work Train.
