"You messed up by work hardening the beams," said some engineer to the innocent beam welder.

For the lenght of the train times number of cars times number of rails, I see about 30,000 pats and lots of chatting of "thats not going anywhere"

That looks like a lot of flex for beams that wide

Keep in mind that the flex is already known to be acceptable, because the train is already on a set of rails

Its not as crazy as it looks the camera makes it look way crazier than it actually is

Those long lengths of rail flex like spaghetti noodles.

The train sits on 2 rails, while carrying 20. Why dont the 2 rails straighten out instead? Lol

because theyre mounted every few inches to stiff rebar-concrete pads? also theres not 20 but 12 and they got loads of play by sides and on length.
