Hi all, after the arriival of BBB wheels, I finally completed the third clockwork locomotive. It is based on pre-war Goods Train No.2 made by Hornby Thanks to BBB wheels reduced profiles it manages well large curves. It works also on R40 radius curves, but looks a lot better on longer ones. The clockwork motor is quite the same as my previous version, only a bit lighter and made all in dark-stone grey color. Two pull-back motors are connected by two red 40-tooth gears, which power the rear big wheels. Motion to front big wheels is achieved trough coupling rods. It has no brake lever, since for winding up you need to keep it on one hand and you can stop the wheels with your fingers. So, being an unuseful weight, I did not include it. It is very light, since the boiler is made by empty cilinders and the body is made by panels. Gear ratio is 5:1 to the axle, then large wheels help to furtherly overdrive the gear ratio. I choose 5:1 since this locomotive will be part of a set, and needs to pull three very small and light wagons. The bolt works as flywheel, and it is put over a little piece of flexible Technic tube. No wheelspin at all allows a bit more travelling. Front wheels on bogie are completely independent, so they make less friction. Front bogie is made to follow the track and not to guide the locomotive, as in old Hornby models. On a mixed track made by straight and large curves it can manage 9 meters with a pair of wagons. I plan to replace the full coupling rods with @zephyr1934 ones, since they are much nicer and surely lighter than mine. Hope you like it! Davide
