I think the answer is a simple question of arithmetic. 600 feet of R type equipment is roughly 800,000 pounds/40 axles = 20,00 pounds per axle. 600 feet of D types = 960,000 pounds/24 axles = 40,000 pounds per axle. So while you may save minimally on car maintenance, our track and structure maintenance would increase dramaticly.
