OK, with proper credit of course. Enclosed is an updated copy correcting a few mistakes and adding some material.
Horsepower is pull times speed.
But there is no horsepower being produced. So we need a loco with at least 29.6 wheels, each of which is weighted to 35,000 lbs. 30 wheels is 15 axles or four 4 axle units minimum. It could also be 3 six axle units which would be 18 axles. Or it could be two 6 axle units and one 4 axle unit for a total of 16 axles.
