Railworks America

I'm just curious, does anyone live near a rail-line that uses the plastic-composite ties? In my area, the rr's aren't even totally sold on using concrete ties, much less trying a bendable one.

Very interesting document. I wonder if they sound different as trains pass over them. I'm kind of skeptical though about the claim that they won't leech chemicals. I saw these being made on a TV program, and they used a binding agent (and molding process) that looked similar to what I've seen used in a recycled rubber mat factory. Those things would leech the binder and ruin the floor beneath within a year of placing them.

I did a little research on this (being in the plastics business) and they go to great lengths to not tell us what these things are made from. I'll see what I can find out. If in fact the resin base is bottle material they will not leach anything out however I am surprised that unless they really load these guys up with UV inhibitor I can't see a very long life on them. That nice little symbol they put on the end of the tie is meaningless. It signify's no recognizable class of plastic.

Polyethylene. Hmmm.

On the Steepest Class 1 Railroad grade in the U.S. (The Paine Field Spur which makes Saluda a Sandbox) uses steel ties
