operates 52 bus routes under the OC Bus brand, encompassing every city in Orange County. Some of the lines also extend to serve the Los Angeles County border communities of Lakewood, La Mirada, Cerritos, Hawaiian Gardens and Long Beach. The longest is route 1 (Long Beach–San Clemente) which utilizes Pacific Coast Highway (State Route 1) for the vast majority of its route, with trips taking an average of 2 to 2.5 hours. South Coast Plaza is the most served location with five OC Bus routes (55, 57, 86, 150 and Bravo! 553). OCTA also operates six routes under the iShuttle (Irvine Shuttle) brand, serving the cities of Irvine and Tustin. These buses have a different paint scheme and fare structure, but still accept OC Bus passes. These routes connect to Irvine Transportation Center and Tustin station, and have schedules timed to give passengers a smooth transfer to/from Metrolink and Amtrak trains.

Additional platforms were added at the Fullerton and Laguna Niguel/Mission Viejo stations to accommodate the additional trains. Metrolink's Inland Empire–Orange County Line began operations in October 1995 between Riverside and Irvine; it was the first suburb-to-suburb commuter rail in the U.S. at the time. The line was later extended and now operates between San Bernardino and Oceanside. Metrolink also added a third line through Orange County on May 6, 2002, the 91 Line, later renamed the 91/Perris Valley Line. The service initially operated between Los Angeles Union Station and Riverside–Downtown station via Buena Park, Fullerton, and Corona, roughly paralleling part of the
