Working backwards, for something like a high-wheeled Pacific or Atlantic, (at 80 inches for the prototype) to run near 100 scale miles per hour:

Gear Reduction Ratio	Motor RPM required
1:18	7,563
1:20	8,403
1:25	10,504
1:30	12,605

For a typical PRR freight engine like a Mike, Decapod, or Consol with 62" drivers and a reasonable 50 MPH:

Gear Reduction Ratio	Motor RPM required
1:18	4,879
1:20	5,422
1:25	6,777
1:30	8,132
