91/Perris Valley Line

The 91/Perris Valley Line, formerly known as the 91 Line, is a commuter rail route operated by Metrolink that runs from Los Angeles to Perris in Southern California, mostly paralleling State Route 91 between Riverside-Downtown and Buena Park stations. Operating since May 2002, the route runs on the Southern Transcon line owned by BNSF Railway, as well as the Riverside County Transportation Commission-owned San Jacinto Branch Line. Services are primarily operated along the entire route between L.A. Union Station and Perris–South, while some trips use Riverside–Downtown as a terminus.
