@RickO posted:Unfortunately, thats not the case. The photos I posted earlier are of the H10 gearbox.
It also has the intermediate shaft visible behind the spokes of the driven axle . However it has the luxury of the removable bottom plate( a carry over from the TMCC tooling) so you can see whats in there:
I took my H10 apart, Lionel 6-84948, and four rotations of the flywheel results in 1/4 turn of the drive wheels. I don't know how you compute gear ratio, but that's how I compute it. I didn't take the motor out, but it certainly does have a 16:1 gear ratio! I don't know exactly what the gearbox looks like inside as I haven't had it that far apart.
