Was reading an old topic in the FEC forum, that concrete ties from 1966 were still in good condition on the FEC main in 2010. Which suggests with easy weather, proper maintenance and a good concrete mix can last nearly 50 years. Of course there are plenty of examples of concrete ties failing much sooner than that, especially in the Northeast where it seems numerous commuter railroads have had their share of trouble getting good ties.
Anyway, out of curiosity, whats the average lifespan of a treated wooden tie?
Further, are there advantages, besides lifespan, that make concrete more appealing?
