The IEOC Line, Metrolink's sixth line to be introduced, opened in October 1995.[3] With the exception of the Anaheim Canyon station, the line shares all of its stations with the 91 Line, the Orange County Line, the Riverside Line, or the San Bernardino Line.

As of July 2016, eight trains in each direction serve the stations from Riverside to Laguna Niguel/Mission Viejo on weekdays.[4] The remainder of the trains servicing the IEOC Line cover more to all of the stations, except San Clemente Pier, which is only serviced on the weekends.[4]

In July 2006, the Orange County Transportation Authority created weekend service on the IEOC and Orange County Lines. As of August 2016, the IEOC Line schedule has two trains on Saturday and two on Sunday, each servicing every station, including San Clemente Pier.[4]

Metrolink's Downtown San Bernardino extension to San Bernardino Transit Center opened on December 16, 2017.[5]
