What you call humped is a condition often called hogged. It would be normal in an unloaded car.
Weight in the middle of the car between the bolsters adds tension on the truss rods and compression
on the wooden frame.
If you observe empty flatbed semitrailers you will see them arched or hogged so that they will
straighten when loaded. Not uncommon to see bridges built the same way as they are stronger
in compression than in tension.
