Track Construction and Maintenance

Perris Valley Line Extension 

Construction of the Perris Valley Line (PVL), which will extend Metrolink commuter rail service on the 91 Line, began in October 2013. Led by the Riverside County Transportation Commission (RCTC), the PVL is the first extension of Metrolink service since the Antelope Valley Line was built in 1994. The PVL will continue rail service 24 miles from the downtown Riverside station to south Perris, with four new stations being constructed at Riverside Hunter Park, Moreno Valley/March Field, Downtown Perris and South Perris. The project also includes construction and rehabilitation of railroad tracks, upgrade of 18 at-grade crossings and improvement of existing tracks. The PVL will provide greater access to Southern California’s commuter rail network for residents in Menifee, Murrieta, Temecula, San Jacinto, Hemet, Lake Elsinore and Wildomar. The PVL is expected to open to riders by late 2015. For more information click here.

Glendale Corridor Grade Crossing Safety Improvements

Metrolink, in partnership with Metro and the cities of Glendale and Los Angeles, are implementing safety enhancements to grade crossings along the Glendale Corridor to meet the latest grade crossing and traffic safety standards. Upgrades include roadway and curb return widening, new automatic vehicle exit gates, new sidewalks and handrails, new automatic pedestrian gates, traffic blank-out signals, and traffic signal advance pre-emption technology. 

The four (4) highlighted projects along the Glendale Corridor that will soon begin construction are at Sonora and Grandview avenues in Glendale, along with crossings at Chevy Chase Drive and Broadway /Brazil St., bordering the cities of Glendale and Los Angeles. At different phases of the projects, an estimated 120 people will work collaboratively to make the sealed corridor a reality.

Upgrades to the crossings, which are projected to be about $17 million, are being covered by the City of Glendale, as well as federal, state and county funds.

Metro, the California Transportation Commission, Senator Dianne Feinstein and Congressman Adam Schiff have all facilitated financial support to make these safety improvements possible.

A new grade crossing project along the corridor was completed at Glendale’s Flower Street in 2009.

The project is scheduled to begin late April 2013 and be completed by early January 2014.
