@RickO posted:There are plenty of Legacy locos with back drivable gearboxes with the traditional worm and axle gear setup. I suspect the extra gears are to allow better low speed performance or get the best performance out of the motor/speed control being used in a particular loco.
Bingo....the tiny ( and horrible Mubachi 385) needs all the help it can get to get good low rpm performance out of it...why in the world they went around their butts and back again to keep that sorry motor in these types of locomotives is a mystery to me.......besides they’re just trying to be cheap.....
