Started putting together a mod for the Hornby 0-4-0 chassis to make it fit a much smaller motor, and hopefully make it slower as well. It seems ok so far, all fits, but not that smooth. Partly as I don't have the proper gears for it yet, so have substituted 3D printed ones.

If this works, then there are a couple of potential bodykits I could make for it that wouldn't have been possible otherwise, with the big motor in the way.
