Train cars have coil springs. They're heavy duty.
Leaf springs are heavy, and have limits with respect to variable rates compared to coils.
No need to ride like a lumber wagon if it doesn't have to. Very few 2500's are loaded 100% of the time. I'd even argue lots of them are not even loaded 50% of the time.
