Metrolink is a rail system based in Southern California that is designed for commuter travel and is made up of 55 stations across a rail network measuring 388.2 miles. The train used in this system travels at speeds of up to 90 miles per hour and is spread through seven different lines across the counties of Los Angeles, Ventura, Riverside, Orange and San Bernardino.
The Metrolink rail system is also connected to other rail systems in Southern California, including the San Diego Coaster commuter rail system, the Sprinter light rail service, the Los Angeles County Metro Rail and with four intercity rail services run by Amtrak. Metrolink was first established in 1991 and started operations in 1992 using trains and engine crews that are supplied by Amtrak.

Of these 55 locomotives, three are leased by Metrolink while the rest are completely owned. Operation of the Metrolink rail system is granted by the SCRRA on five year contracts. Metrolink also operates three maintenance facilities throughout its system, which are the Central Maintenance Facility, the Stuart Mesa Maintenance Facility and the Eastern Maintenance Facility.
