The Fullerton Depot is one of the busiest passenger train stations on the West Coast. All passenger trains that serve the Fullerton Depot are arranged in the above list ordered by the times that each train is scheduled to leave the station. There are also many BNSF freight trains through the station all day and all night.

Note: All Surfliner trainsets have been delivered to Amtrak and are operating on the Pacific Surfliner route. However, there are still a few single-level trainsets in unscheduled operation.

Trains stop at more stations than those listed above. The only stations listed are ones that are end-points for some runs and Fullerton. "..." as a place holder means the train route ends at the last listed station to the right or left of the place holders.

If you are standing on the platform closest to the Fullerton Santa Fe Depot building and facing the tracks, "-->" and "<--" indicate which direction the train will enter and leave the station. Although the orientation of the station is really east/west and all trains through the station have a strong east/west component in their direction of travel, trains heading for San Diego are considered "southbound" and those heading for Los Angeles are considered "northbound". The only trains considered to be "eastbound" or "westbound" are the trains heading from or to Riverside and San Bernardino.

Generally, all Northbound, Eastbound and Westbound trains arrive on the track closest to the station. All Southbound trains arrive on the track furthest from the station which can be reached by crossing over the pedestrian bridge. Elevators and stairs are available at each end of the pedestrian bridge. There is a center track going through the Fullerton Station which is only used by freight trains. Passenger trains never use the middle track.

WARNING: Freight traffic is heavy in Fullerton, and freight trains can go through the Fullerton Station on any track in any direction at any time without warning! Stay well away from the edge of the platform until the train you are boarding comes to a complete stop.
