Les - the rail contains steel. A table saw would be dangerous in any event. That's how people lose a hand or eye or worse. Steel can be cut if firmly clamped into a "chop saw" with either a metal-cutting abrasive wheel in it (typically 14-inch diameter), or a special steel-cutting kind of carbide blade on the same kind of chop saw. Don't confuse this with a wood-cutting mitre saw; using one of those could also result in serious injury. Hacksaws are for hacks. Sloppy, crude, and archaic; but if precision and neatness of cut is not the objective, yes, it would work. The company I worked for started out as a supplier to the Navy (there were big military shipyards all around here back then). I sold them very few hacksaws, but thousands of heavy-duty metal-working power tools over the years. Most metal working shops and even some plumbers have clamping stands for portable power bandsaws (essentially a power-hacksaw, not to be confused with wood-cutting bandsaws) which would work, but not nearly as well as a rotating "chop saw". But there is proper technique to all of this; otherwise a person can get seriously hurt.
