Scarce 1927 Principles of Railroad Transportation by Emory R Johnson, PhD Railroadiana Early US Transportation

This 1927 foundational text by University of Pennsylvania professor Emory R. Johnson traces American railroad development from stagecoaches through the modern rail system, illustrated with maps, diagrams, and photographic plates. The scarce first edition is in very good condition with its original red cloth binding intact, though the covers show age-appropriate fading and spotting. A substantive addition for collectors of transportation history and early American industrial documentation.
