The southern terminus of the Pacific Surfliner and a historic union station where intercity, commuter, trolley, and regional railroad histories meet.
Overview
San Diego is the southern anchor of California’s coastal passenger-rail network. The historic Santa Fe Depot in downtown San Diego serves Amtrak Pacific Surfliner trains, NCTD COASTER commuter service, San Diego Trolley lines, buses, and connecting transportation.
San Diego also has a second major mainline passenger stop at the Old Town Transportation Center, where Pacific Surfliner, COASTER, trolley, and bus services converge. A new downtown COASTER platform is planned near the Gaslamp Quarter, Petco Park, and the San Diego Convention Center.

Historical Background
California Southern and the First Depot
San Diego’s earlier passenger terminal was a Victorian-style station built in 1887 for the California Southern Railroad. The California Southern’s original route ran from National City and San Diego north through Oceanside, Fallbrook, Temecula, and Perris to the Inland Empire.
The 1915 Santa Fe Depot
Santa Fe built the present depot for the 1915 Panama-California Exposition. The building’s twin towers, tile domes, arcades, and Mission and Spanish Revival details created a monumental entrance to the city. The depot was listed on the National Register of Historic Places on June 26, 1972 (No. 72000248).
A Union Station in Practice
Although commonly called the Santa Fe Depot, the downtown station functioned as a union station because it served trains of more than one railroad. In addition to Santa Fe trains, it served the San Diego & Arizona Railway, completed in 1919, and later the San Diego & Arizona Eastern Railway.
The San Diego & Arizona route toward San Ysidro, Carrizo Gorge, and El Centro became famous as the “Impossible Railroad” because of the difficult terrain and engineering required to build and maintain it. This shared use explains the station’s historic Union Station identity and connects downtown San Diego with the Pacific Southwest Railway Museum at Campo and future WRA coverage of Carrizo Gorge.
The Amtrak Era
Amtrak preserved intercity passenger service at the depot with the San Diegan, renamed the Pacific Surfliner in 2000. The Pacific Surfliner now terminates in downtown San Diego after traveling through Oceanside, Orange County, Los Angeles, Ventura County, Santa Barbara, and San Luis Obispo.
Santa Fe Depot / Downtown San Diego
The downtown depot remains the city’s principal historic railroad landmark and a major multimodal terminal.
Pacific Surfliner
Santa Fe Depot is the southern terminus of the Pacific Surfliner and supports terminal operations, passenger boarding, equipment layovers, and transfers with local transportation.
COASTER
COASTER trains currently serve Santa Fe Depot, linking downtown San Diego with Old Town, Sorrento Valley, Solana Beach, Encinitas, Carlsbad, and Oceanside.
San Diego Trolley
Trolley platforms at the depot connect intercity and commuter rail passengers with San Diego’s urban rail network.
Old Town Transportation Center
Old Town is San Diego’s second principal mainline passenger station. It is served by the Pacific Surfliner, COASTER, San Diego Trolley, and numerous bus routes.
The transportation center provides an alternative to downtown San Diego and direct access to Old Town San Diego State Historic Park and Presidio Park. Unlike the staffed Santa Fe Depot, Old Town is an unstaffed, platform-only Amtrak stop without a ticket office or checked baggage.

New Downtown COASTER Platform
NCTD is planning a new COASTER station parallel to Harbor Drive near the Gaslamp Quarter, San Diego Convention Center, Petco Park, and the Rady Shell. The project is intended to provide a one-seat ride from North County to these major downtown destinations.
The project includes an 850-foot passenger platform between First and Fifth avenues, a new siding or pocket track, reconfiguration of existing BNSF trackage, railroad switch and signal upgrades, grade-crossing improvements, and pedestrian and bicycle safety work.

Western Rail Archive Notes
San Diego should become a cornerstone WRA page. Its final form should clearly explain the distinct roles of Santa Fe Depot, Old Town, and the new downtown COASTER platform while connecting the city’s modern rail network with the California Southern and Impossible Railroad stories.
