Sean Thul AAR loading rules normally require that loads such as those gears be no less than five feet from the ends of the car. Only on highway trucks are loads positioned over the wheels. Railcar frames are of sufficient strength that loads are intended to be placed in the center of the car to distribute the weight evenly over both trucks.
here is my schnabel car i finally got done painting after i had absnut build it last year. not real proto on the paint but oh well.
Great paint job!!!. Usual speed for a car like that is 15 MPH. Really slows down other traffic, gets out of the way of EVERYTHING. Whoever is expecting that load on your car better not be in a big hurry to receive it.
