Metrolink connects with Los Angeles County's Metro Rail and Metro Busway systems, North County Transit District's Coaster commuter rail and Sprinter hybrid rail services, and with Amtrak's Pacific Surfliner, Coast Starlight, Southwest Chief, Sunset Limited, and Texas Eagle inter-city rail services.^[5] Metrolink owns several hundred miles of track; however, it also shares track with freight railroads.

The system, founded in 1991 as the Southern California Regional Rail Authority (SCRRA) and adopting "Metrolink" as its moniker,^[6] started operation in 1992. Average weekday ridership was 42,928 as of 2017.^[7] The SCRRA contracts with Alstom both to operate the trains and to maintain the rolling stock (locomotives and passenger cars).^[8]
