Hoping to avoid traffic on Highway 91, the La Sierra Metrolink Station has been a destination for bus riders and train passengers for more than 20 years. Due to its expansive parking area, the station is the second-largest station served by Metrolink, the largest being Union Station in downtown Los Angeles. It’s nicely landscaped and always clean. The station debuted in 1995 along with the opening of the Inland Empire-Orange County train line. It is also a popular destination for people riding the new 91/Perris Valley Line.
