Can the ball of a section of 110 pound railroad rail be hardened in some
manner,
to be okay to be used as dies in a 60-75 pound treadle or power hammer?
If not what is the best way to obtain the proper metal for the dies?
in advance thanks...

What kind of dies do you need?
I just aquired some used HSS punch tooling, and I might be able to
spare one or two of the bottom dies, provided a slot or hole in the
middle doesn't make them unusable for a power hammer.

It's 1075 to 1080 straight high carbon steel, the same as a quality
cold chisel is made from. For the most part railroad rail is some
of the better and cleaner steel of that type ...for it's time. :)
There are few others a "Hi-Si" and a "Cro-Mo" but bet that 110lb
ain't one of them... but if it was, it'd heat treat the same anyway.

Cool. :) Hunks of that scrap HSS, used as-is, is going to get a lot
of work done! :) Just try real hard not to lose too much money on
it while re-distributing it, Proc. ;)

1000 series steel.... heat to 1600, quench in water or oil, draw at 375 to
400 for two hours, cool to ambient, go to work. Should deliver a final
Rockwell in the mid fifties C scale. All temps are farenheit. Merry
Xmas...
