How did you come up with THAT???? My information has the Santa Fe 2900 class 4-8-4s at 293,860 lbs weight on drivers, while a UP 4000 class 4-8-8-4 has 545,200 lbs weight on drivers.
Now, the axle loadings on the Santa Fe 2900 class is a whopping 77,500 lbs per axle, while the UP 4000 class is only 67,800 lbs per axle.
I apparently misunderstood what I was reading. Something is the first to go, I just can't recall what it is...
