Chassis and gearbox for 1910 Greenly designed Great Northern Gauge 2 0-4-0 Saddle Tank. This model was originally electric when made in 1910 but came to me without chassis or mechanism. The outline follows Greenly's design and the mechanism is a modern 385 motor driving through my standard bevel wheel gearbox. Power is supplied by 2x 26650 Lipos and running time is several hours (at least).

These components are designed to work in an existing body shell designed by Henry Greenly in 1910. Although a G2 model, the gearbox will fit between G1 frames and accepts 385 or 540 size motors.  The axle is 1/4" plain bearing but alternative designs for ball raced 1/4" or 3/16" axles are available.

You can see the model running on 11/12 March 2023 at the Garden Railway Show, Leamington UK here: https://www.youtube.com/watch?v=lMSOXkzyKBg
