I love the Nelson Rain Train. I have three of them. Every few years I have to replace the gearbox on each one. But there's really only one gear inside that fails. It's in the top of the gearbox on the right side. If I could get a replacement of that one gear instead of having to replace the whole gearbox that would be great! (And I dare say it would be easier to fix than removing the wheels from the old gearbox and putting them onto the new one.)

If I could just replace this one piece (pictured above) that would be all I'd need to do. It's just that nobody sells that one gear all by itself. Or, at least, -I- can't seem to find a way to buy just that one gear.
