I read somewhere that recycled plastic railroad ties work better than wooden ones. Would be a handy way to rid ourselves of some of the plastic that ends up in landfills.
Concrete seems to be the preferred choice, and for high-speed lines, the only choice. I’m guessing that places still using wood do so because it’s cheaper and line speeds don’t need anything better.

And possibly create lots of small plastic fragments from the friction with the stones.
Meh. Better than cutting down trees and covering them in arsenic and benzene that leeches into the soil.

These look like concrete to me?
