And a quick photo update of the loco, construction in progress
The track is actually 3mm scale FS, i.e. 14.2mm gauge, that is more or less the right gauge and I had this display piece knocking around.
The extended cab is not quite Brede, deliberately so, and the reason it is made from Plastikard is that it is intended to employ radio control. I will put more detail in a specific blog entry but this loco has a 3v motor, will have a 3v LiPo battery inside the boiler and a WiFi transceiver/controller chip in the coal bunker. The thin wire antenna will poke up into the cab space, hence the Plastikard upper sides rather than brass ones. I need to make a bigger smokebox and craft a better saddle for it than the cast one from the kit. Plus getting all the waggly bits of the motion sorted out.
