K1 All Ready for Departure

I’ve been building a model for a client back in the UK. It is for locomotive K1, one of two K class garratt articulated locomotives built by Beyer Peacock in 1909 for operation by the Tasmanian Government Railways. These were the first ever garratt class locomotives built and the first one, No K1 was repatriated to the UK and now lives and operates on the restored Welsh Highland Railway in North Wales. More information on these locomotives can be found here and here.

I was asked to build a model of this loco for a client in OO9 scale. This is the same that I model in and is 4mm/ft (OO scale, 1:76.2), with 9mm (N-gauge) track. This results in a narrow gauge model. I’ve always wanted one of these locomotives for the railway, so ended up building two in parallel. The models were based on etched brass and nickel-silver kits by Backwoods Miniatures, though I modified the kits with a certain amount of scratch building including replacing the boiler barrel, new firebox front sculpted from brass and new smoke-box door. These were certainly tricky models to build and get running well, but the first one is now finished and ready for dispatch to it’s owner in the UK. The locomotives is equipped with DCC control, which drives two motors, one for each power bogie. Valve gear is functional and the locomotive is outside framed with both axles of each power bogie driven through a layshaft worm / gear drive. The full story of the build can be found here, though you may need to register to access the content. The boiler unit of my own locomotive has been completed, as have the front and rear tanks, and work is ongoing on the two powered chassis units.

So without further ado, attached are some pictures of the build.

So there we are. A very tricky and frustrating build, but it finally yielded a decent model. I hope my own comes out to the same standard.

It will go in the mail tomorrow and i hope the client is pleased with it. Now to finish my own loco and on to the next project…….

(PS and by the way i hate this new WordPress – it makes it very difficult to lay out pages with pictures correctly. There, I’ve gotten that off my chest now!)
