 The station was listed on the National Register of Historic Places in 1975 as "Southern Pacific Railroad Company's Sacramento Depot".For most of Amtrak's first two decades, the only trains calling at Sacramento were long-distance routes.The "California Zephyr" and its predecessors have served the station from Amtrak's inception; several pre-Amtrak predecessors of the "Zephyr" stopped in Sacramento from the 1930s onward.
