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