[9] Oceanside Transit Center is also served by Greyhound Lines and numerous NCTD BREEZE buses.

Oceanside Transit Center was built in 1984, and serves as a replacement for a 1946-built Santa Fe Depot, which was torn down in 1988.

This station became one of the original 9 stations on Metrolink's Orange County Line when that line opened on March 28, 1994, and North County Transit District's COASTER commuter rail began serving this station when the line opened on February 27, 1995[10] and Metrolink's Inland Empire–Orange County Line began serving this station regularly in the early 2000s after serving the station on a temporary basis from that line's opening on October 2, 1995, until the early 2000s and North County Transit District's SPRINTER hybrid rail service began serving this station when it opened on March 9, 2008.

[11] To enhance the regional transit service, this station underwent a major expansion including building a third track and platform in the middle of the existing tracks, extending all platforms, and adding a passenger walkway.
