Just for fun I motorized it using the motor from an old cordless drill I had .I used one of the nylon planetary gears to engage the brass motor gear.I had to use a tapered reamer to bore it out to accept the drive shaft.

Yes the first link is correct!

I had to shim the motor to achieve gear lash so it doesn't tear up the nylon gear .

Now I have to find driver's with one having the main drive gear and front and rear trailing trucks and appropriate valve gear .
