I just had the good fortune to have a freind give me a copy of a book called " A Treatise on Wooden Trestle Bridges" published in 1913. It appears to have all the latest info at that time as far as engineering and design of large trestles such as we had on the Curry Branch. I can't imagine what the cost of a large wooden structure would be today. Has any railroad in recent times built a large wooden trestle? It would seem to me that with the high cost of lumber products, and with the susceptability to fire it would make sense to rebuild the Curry Branch trestles with steel. This is of course after the Oil Czar wins a whole unit train of cubic dollars in the Lotto and gives it to the SVRy.
