I have been led to believe that many box car interiors and possibly floors were of white oak. A woodworker once asked me if I knew where any boxcars were being scrapped (i.e. in the Antelope / Roseville area), as they were often a source of good-quality recycled oak.

True for many railroads. SP often specified Douglas fir or yellow pine, since both could be obtained from on-line mills, and are also durable woods.
