Railroad Ballast: Why Is Such Aggregate Necessary?
If you ever happen to take a closer look at a well-maintained railroad right-of-way be sure and notice how the ballast system works, aside from the stone and technical layout. To either side of the railroad track below the ballast you will notice a well-groomed ditch that carries away all of the water which drains from the railroad track structure.

Rock to railroad
It is not the best rock, but it is rock. It is not something you want to use on a daily basis. There is great sport to be had in researching the different materials used as ballast over the decades; for example, cinders, and even slag has been used. "Slag is good stuff, but it is so hard it would damage the ties," Poh says.
