They have a section on their web site which will give you contacts for technical specifications.

Interestingly, in hte 70's there were many railroad wheels cast with too much carbon in them, causing premature failure. They used to stencil a big black square with either a white or yellow circle on them. I think the white means it was shopped and the wheels replaced, the yellow meant it had the crack susceptible wheels.
