OOOOOoooooops. Lather, if the contact area gets larger and the gross vehicle weight is static, the pressure per square inch decreases due to the same amount of weight being distributed over a larger area.

<<I know locomotives are heavy mothers. Like those articulated jobbies that came just before diesel electrics. Five hundred tons wet, if mammary serves.>>

Ain't it amazing those big diesel electrics do the same as hand cranks on the old telephones. Same on large ships.

<<But those had very large wheels, and I would allow that the contact patch between wheel and rail grows proportionally. So pressure probably goes up some but not a whole lot. From 12 gauge to, say, 45 auto. <g> >>

Got one for you smart guy. I don't remember the answer but I remember that a woman in high heels, puts many times the pressure in PSI as an elephant does on the flooring. It was like 100 times.
