a little unknown tie product, is compressed recycled plastic ties,
this was developed in thailand,
i believe, due to that country's notorious humidity, met the
president of the company, when he was doing
a cross country sales tour, over here, the price is cheaper than
wood, and allegedly lasts twice as
long as the concrete ties, it's big in thailand, but doesn't seem to
have caught on over here

The biggest problem with concrete ties is the fastening systems to
the rails. Either they shake loose or break under the loads of the
trains. SAL used them in industrial areas and on ballast deck
bridges back in the 1960's, but the screw fasteners would break and
could not be removed to be replaced. The newer systems with Pandrol
spring fasteners holds tight but the steel rail grinds the concrete
tie down till the fastener looses its hold. We tried a plate under
the rail that helps in straight track but not in curves. The
advantage of concrete ties still needs to be improved and the price
kept competative to other materials.
