Input: Question: What is the total length of the light rail service operated by the  Los Angeles County Metropolitan Transportation Authority? Passage:The Los Angeles County Metropolitan Transportation Authority (LA Metro) operates the Blue Line, a light rail service that runs between the Downtown Long Beach Station (known as the Transit Mall Station until July 2013) and the 7th Street/Metro Center station in downtown Los Angeles. From the 7th Street/Metro Center Station, passengers can make connections to Hollywood, Union Station, Pasadena, East LA, Universal Studios, Chinatown, and other points of interest along the Los Angeles Metro Rail network. From Union Station in downtown L.A., transit users can access the regional Metrolink (Southern California) rail system to access a vast area of urban Southern California, and connect to nationwide Amtrak trains as well. The Metro Blue Line also offers connections to the Metro Expo Line at both the 7th Street/Metro Center Station and Pico Station with service to Santa Monica. In addition, at Willowbrook Station, passengers can transfer to the Metro Green Line with service to Redondo Beach, Norwalk, and Los Angeles International Airport via an additional shuttle connection. The Metro Blue Line Maintenance Shops are also in Long Beach just south of the Del Amo Blue Line station.
