This is, without doubt, the model of which I am most proud.
The true joy of scratch building models is knowing that you have made something completely unique, and that is most certainly the case with the Welsh Highland's tamper.
The KMX was purchased in 2005 at the start of the final push to Porthmadog. As bought it was a metre gauge machine (built in Austria in 1995 by Plasser & Theurer's French subsidiary FRAMAFER for use in an underground coal mine in France.
It was taken to Boston Lodge where the complex task of overhauling and re-gauging it began, with Bron Hebog blog reader Chris Hoskin taking a leading role. (So I shall not show my ignorance by writing any more about that here!)
Our model was scratch built in styrene and brass (the roof) and motorised using a Kato Shorty chassis which had one bogie removed and mounted independently as a trailing bogie at the other end of the model, but wired through so it could still pick up current.
Like many of our models it was a team effort, with me building most of the styrene body, and Himself fabricating the roof (one of the many Boston Lodge alterations) from brass and taking on the job of painting and weathering it.
It was something of a stop - start project which took the best part of three years from the first cutting of styrene to it's debut on Dduallt in May last year.
