Not sure this is the right place to post being as the questions pertain to real not model trains. For those that didn't see my "Took any other hike" thread, this is 40 lb. rail off a narrow gauge railroad that would have ceased to exsist by the mid 1940's at the latest. #1- Why does it have a reddish cast? Is it iron not steel rail? If so what does that say about it's age?
