I just wrote about a small home-made power truck for HO locos.
It occurred to me that there a variety of small tender-drive locos made by Bachmann (the Jupiter), Rivarossi / Pocher, etc. which may have missing or burned-up motors. It might be possible to shoehorn a Tyco power truck under the tender shell. Perhaps the magnet in the top of the power truck could be disguised by a pile of HO scale logs on top of the tender. The F7A side frames could be replaced with archbar side frames which would disguise the F7A diesel wheels.
