We just had this strange loco come in as part of a collection at our local train store. It is an electric, 3-rail, O gauge loco, made out of something really heavy like cast bronze. It weights at least 15-20 lbs. It has twin open frame AC motors, and what appears like postwar Lionel pantographs. The drive mechanism consists of a worm gear driving one axle which connects to the other axle with a chain drive.
Has anyone seen anything like this before? Is this part of a small production run, or just the work of someone very dedicated to scratch building something very unique?
