Pretty simple really for a start, just put a flat on top of a piece of rail track to use as an Anvil.

Welcome to the forum Tom, How did milling railway line go? Rails are made of extra-tough steel, and make good anvils, but I'd expect one to be difficult to machine. Perhaps not, I've never tried.
Be wary of machining unknown scrap metal because some of it is difficult to cut, too soft, too hard, gritty, sooper-tuff, brittle, etc. If scrap cuts badly – poor finish is a common symptom – don't assume the machine, cutter or operator are the problem. It's safest to start with known metal where the specification mentions good machinability or 'free-cutting'. Once used to cutting machinable metal, it's much easier to recognise and adapt to an uncooperative alloy. Have fun!
