Clayton battery locomotive.
Mostly I've been writing a long list of all the small issues I've found with the current design now I've got the first prototype print in my hands. It's turning into quite a long list, but fortunately most of them can be solved on the current print with a little bit of thought, which allows me to test the changes before ordering another print. Before I can assemble and test the locomotive though I need some track to run it on.
If you remember I'm building this model in O14, 7mm to the foot scale running on 14mm track to represent 2 foot gauge track, as the loco is too small to model in my usual scale of OO9. The problem is I've never modelled in O14 so I didn't have any 14mm track. Fortunately I'd planned in advance for this and ordered some roller gauges from KBscale. Given that I'm short on desk space I decided to produce a test track that would let me test both O14 and OO9 (O9 and Gnine as well if I wanted to branch out) models, so I now have a 60cm dual gauge test track.
