The term Harriman refers to railroad equipment built in the 1900’s and 1910’s to a set of common standards that were used by the Harriman controlled Southern Pacific and Union Pacific. The coaches are 72′ 0″ long over the end sills, 9’9-7/8″ wide, and 14’0″ from rail to top of roof. They are 80’8-7/8″ long from coupler to coupler. Each coach weighs 119,900 lbs. without passengers. The coaches are constructed on a steel frame with steel channel and plate used throughout. The coach floor is poured concrete, which provides a smoother and quieter ride.
