I dunno if it's an optical illusion, but I feel like you can see the tracks buckling under the wheels on account of the incredible weight.
They do visibly pump with each car when the ties aren't tamped well on clean rock. I doubt their hand-laid tracks were as easy to get right as we can with extra rock and a modern surfacing gang.
Also rail weight has gone up an astonishing amount over time. Rail used to be puny compared to what is used now.
Guess the 30% spec didn't exist back then, or they decided it to be acceptable.
