I was driving through Coachella Valley along the railroad line that comes out of the LA area. They were triple tracking the line and I noticed that the new ties were concrete. I know that concrete ties have been tried in the past without much luck. This is one of the heaviest traveled RR lines in the country (the reason they are triple tracking). It seems that concrete would not be able to take the constant flexing like wood does. Any thoughts?
