I occasionally happen across bits of railroad track and mounting
plates. Is any of this stuff machinable?

Yes, I've had good luck machining railroad steel, everything I've tried.
Welds OK too. I have not tried track but lots of guys mill the top off
of a bit of track to get something to pound on.

By the way, like many other things the company that sells things to the
railroads has an online catalog. Handy to look up track data:

I don't know how much of it is still around but years ago I remember
trying to use track plates and spikes that were so old that they were
made of wrought (forged) iron instead of steel. They were difficult if
not impossible to cut with an acetylene torch and welds often broke
because of the laminar structure.

Thanks, I see it when I'm out hiking and have not wanted to haul it
home if it was worthless stuff.

In Japan, most of the railway stations have
structural components made from old rails.
Seems to cut, drill and weld fine for them.

It is steel is it not?

Yes, it is machinable.

But there are "issues" with working with railroad rails, mostly having
to do with work hardening of the bearing face, the place where the wheels
roll on the rails. The home machinist means of fixing this is to put the
piece of rail in your fireplace, build a nice fire, and let the metal
anneal over night. Remove, clean up and mill as per normal.

... or just use carbide tooling

A kid brought me over a 18" section of really heavy rail to make an
anvil out of. Clamping it down to the table of my MasterMill, I
installed by very best carbide inserted face mill, calculated speeds
and feeds and melted off everyone of those teeth in about the first 8
inchs.

that **** is HARD.

We finally finished it, and it came out nice..but the second one he
did..we did the bonfire trick and it machined like annealed 440c.
Sweet job to machine once its been annealed and all that work
hardening is softened up.
