Completed and occupied on August 1, 1927, the Southern Pacific Depot was designed by Southern Pacific Railroad architect Leonard B. McCoy and built by Ward Construction of El Paso as part of a major railroad expansion into South Texas. Edinburg experienced positive economic effects when the railroad began shipping citrus and vegetables and serving passengers' needs. Passenger service ended in 1952, though freight service continued until 1982. The depot is a fine example of Spanish Colonial Revival architecture, with features including double entries, tile detailing, and built-in benches.
