Train related question.

When we were kids we use to walk along the train tracks. Around the rails and between the rails there was something that looked like chunks of iron and steel laying all over the place. This was back in the 1950s. It was everywhere there were train tracks and this was in Northern Calif. What was this stuff ?

you would rarely find them that looked like lava rocks made of iron, the coke plant was miles away on the other side of the mill
Before the vast improvements in dynamic braking, a train would stop before descending a long, steep grade and the brakeman would set "retaining valves" on a pre- determined number of cars according to % grade and train tonnage.
This would prevent the brakes from releasing on the selected rail cars.
Depending on how well maintained the brake assemblies were, this could, of course, eventually cause the brake shoes to burn off until the brake head and wheel were metal to metal.
* would build up until the pounding of the rail would cause it to fall off.
Or, the brakeman might knock it off after the train reached the bottom of the grade and he went back to reset the valves to their exhaust position.
Just a wild guess![;)]
Thank steam locomotives running hard with very hot fires and lots of draft. Clinkers are in essence the result of non flammable impurities in the coal which have been liquefied, cooled, then dumped onto the track bed.

When my kids were young, I used to tell them at Christmas time to behave, or Santa Claus would leave them a stocking full of natural gas. (They've never seen coal, probably wouldn't know what it is.)

The second time you get caught will not be so easy.
The insulators along the tracks are COLLECTIBLE, and worth so much more than a medium for creating phony arrowheads. Date nails, post nails, Osmose nails, certain spikes, and cutoff hunks of track are all valuable to railroadiana collectors. Some of the ancient barbed wire in the fences is also collectible.
If you insist on trespassing on R/R property, take at least one other person with you to watch for trains; that's how you get home alive with all your stolen booty.
