Coast Line (Union Pacific Railroad)

The Coast Line is a railroad line between Burbank, California and the San Francisco Bay Area, roughly along the Pacific Coast. It is the shortest rail route between Los Angeles and the Bay Area. Though not as busy as the Surf Line, the continuation of the Coast Line southbound to San Diego, it still sees lots of passenger trains, especially because of that of the Pacific Surfliner, which runs from the San Diego Santa Fe Depot to San Luis Obispo via Union Station in Los Angeles, is the third busiest Amtrak route outside of the Northeast Corridor between Washington D.C. and Boston, which in turn hosts two of Amtrak's busiest routes being the Acela and the Northeast Regional.
