Irvine is served by commuter rail to Los Angeles, San Diego, Riverside, and San Bernardino counties at both the Irvine and Tustin stations of the Metrolink Orange County Line and the IE-OC Line. OCTA is currently implementing a major service increase on the Orange County line, with trains approximately every 30 minutes during weekday commuting hours. Amtrak trains run approximately every 60 to 90 minutes all days of the week along the Pacific Surfliner route between San Diego and Los Angeles. Amtrak trains stop only at Irvine station, unlike Metrolink, which stops at both Irvine and Tustin station. Rail2Rail monthly passes allow commuters to use both Metrolink and Amtrak services, standard tickets are specific to a single operator. A four-story parking structure was recently completed at the Irvine station as part of a station renovation.
