Route map

The 91 Line is a commuter rail line operated by Metrolink that runs from Los Angeles to Riverside in Southern California, paralleling State Route 91 between Riverside and Santa Fe Springs. Operating since May 2002, the line runs on the Southern Transcon track owned by BNSF Railway. The 91 Line has five trains each way on weekdays and none on weekends. As of April 2010, the line shares all of its stations with the Orange County Line and Inland Empire-Orange County (IEOC) Line. The planned Placentia station will be the first station only served by the 91 Line.


There are eight stations on the 91 Line:[2]

The stations at West Corona, North Main Corona, Riverside-La Sierra, and Riverside-Downtown are also served by the IEOC Line; the station at Riverside-Downtown is also served by the Riverside Line. Although the 91 Line follows the same route through Los Angeles county as the Orange County Line, the 91 Line does not stop at Commerce station.[3]

A new Placentia station will be built to serve the 91 Line's north Orange County passengers; this station is in final design with construction to begin in 2012 or 2013.[4] This will be the only station on the 91 Line not shared by another Metrolink line, until the Perris Valley extension is implemented.

Perris Valley Line extension

The Perris Valley Line is a 24-mile-long extension of the 91 Line into the Perris Valley being planned by the Riverside County Transportation Commission (RCTC).[5] As of February 2010, the extension is scheduled to begin service by 2013.[6] The extension will run on the San Jacinto Branch Line, which parallels Interstate 215.[5]

Planned stations

As of August 2013, four new metrolink train stations are planned for the extension:

Seven stations were originally planned by RCTC—five to open along with the extension, and two to be built in the future. However, in the April 2010 CEQA-mandated,[8] three stations were dropped: the two future stations, one on the Cajalco Expressway near its junction with Interstate 215 in Perris and one in Box Springs within Riverside, and a station near UC Riverside, which was removed due to complaints by local residents.[9] In response to these removals, RCTC officials stated that more stations could be built in the future if necessary.[9]


RCTC bought the BNSF San Jacinto Branch Line in 1993, soon after Metrolink began operating.[10] Planning for the extension formally began in 2002. After studying the service alternatives available for the Perris Valley, RCTC selected commuter rail service in 2004. The Federal Transit Administration provided funding for the extension in 2007.[10] In 2009, both the Federal Transit Administration and RCTC decided to conduct further studies into the project. The Federal Transit Administration decided to require a Supplemental Environmental Assessment (SEA) to refresh the 2004 information and to obtain new public comment. RCTC had decided to prepare a full Draft Environmental Impact Report (EIR) to clarify concerns and address new station site options. The Draft EIR was released for public comment on April 5, 2010, with the public comment period closing on May 24, 2010. The Draft SEA was completed and the comment period for the SEA ended on January 6, 2011. As of October 2012, comments received on both the EIR and the SEA are under review.[10]

In the August/September issue of

Future development

In 2005, an RCTC-commissioned study determined that extending the line to San Jacinto via an underused rail line and/or Temecula via a brand-new trackage would be feasible.[11]
