I have one also, its “close” to 1/29ish, looks great parked on a siding. I thought it would look best as a weathered graffitied parked or abandoned switcher being stored at a yard, something we’ve all seen in reality but no one wants to model an “abandon” at $300 an engine, well now you can…
It is unpowered, very thick plastic rails, toyish in detail, has train sound buttons, is made by New Ray in China. It is G in gauge and rolls OK even on R1s. As I said all rusted up and covered in Graffiti would look great parked at the end of a siding.
At some point in its development it appears to have had provisions for a motor in one of the trucks, but it was never installed as such, most likely was they did a few with a cheap motor, then tested them using the freight cars from the G train sets they currently make, and found it couldn’t pull them worth beans, so they dumped the idea of a train set and are selling them off unpowered as “push toys” .
