Hi
I have the Ernie Shepherd book and can give you some information that may help;-
Class K3 0-6-0 no 356, supplied by North British Loco Company, modified to 2-6-0 due to problems on the bends. Bullied and his team modified it as the test bed for turf burning, it ran on the tracks all the way to Cork and back, it went through many changes during testing and was eventually sidelined as CC1 came on line.
Shepherd's book has a chapter on 356 with many fascinating photographs of her in the workshop and out under test. If thinking of modelling this loco, this book is a must. One stunning photo is of the modified loco, its tender, and a wagon trailing behind with a Layland bus engine on it, used to provide assistance in the drafting- now there's a model?
Prior to 356 being set up, Bullied and the team ran tests on burning milled turf in the lab and in the Icnhicore Power House boilers and 356 was the follow up to that.
I plan a Gauge O model of this loco, I find it more interesting than CC1.
