Mark's rendition (above) got me off and running. Completed Saturday afternoon. K-Line die cast 13" Santa Fe flat car with the weight removed. Four wood rails and a load of 2 rail wheel sets. The wheels nearest the centerline of the flat car have a dollop of rubber cement to reduce vibration. What does the average prototype wheel set weigh?"
When you consider each wheel is anywhere from 33 to 36 inches in diameter of solid steel, then each wheel set would easily be several hundred pounds.
