A 45mm gauge "Jennie" 0-4-2T by Roundhouse Engineering, a design described by its makers thusly:

Jennie is ideally suited for those looking for something in between our smaller basic engines and larger classic engines. Personalise it to your own requirements with the additional parts and accessories available.

In this case the personalisation included side tanks and open cab - it could be used as-is, or re-modelled to your own preferences.

Rolls freely, it ran in either direction under steam.
