Central Maintenance Facility (CMF)
The property where Metrolink’s Central Maintenance Facility (CMF) is located, previously known as Taylor Yard, serviced locomotives and rail cars since the 1920s. Metrolink operates 365 days a year. The Central Maintenance Facility (CMF) provides a critical function for Metrolink to provide this regional service. CMF is one of two service, inspection and repair facilities in the Metrolink system and the only facility equipped to handle heavy maintenance and repair. Following early morning peak runs, nearly all Metrolink trains arrive at CMF to be inspected, tested, fueled, cleaned and serviced for afternoon departures. Metrolink is committed to meeting the transportation needs of the region in the safest and cleanest way possible, while being a good neighbor to the surrounding communities.
CMF is one of two service, inspection and repair facilities in the Metrolink system and the only facility equipped to handle heavy maintenance and repair. Following early morning peak runs, nearly all Metrolink trains arrive at CMF to be inspected, tested, fueled, cleaned and serviced for afternoon departures. Testing usually takes between 45-60 minutes, but may take longer depending on equipment arriving for service, as any defects needing to be addressed prior to departure are corrected. During the inspection and testing process, the locomotives are required to be running to perform various functional tests mandated by the Code of Federal Regulations 49 Parts 200-299. More details about our operations can be found in the CMF factsheet:
CMF DIAGRAM KEY

Description: For the last two years we have been working to improve our relationship with the CMF community. Recognizing that noise is a community concern, Metrolink decided to place Permanent Sound Monitors in both the community and at the facility to allow transparency. Two monitors have been placed in the community with the access to the live data provided at our website and two installed in the yard for comparison, a total of four monitors.
Disclaimer: Street noise such as trash trucks, ambulances or tree trimmers can impact the sound monitor readings. The monitors at the CMF will serve to measure noise at the yard and will be compared to the community readings.
Note: The dB(A) is a unit of measurement for noise that is perceived by the human ear. The dB(A) is used by The City of Los Angeles to determine compliance to noise standards and is the A-weighting of the standard sound level that is measured in decibels (dB).
Train movement and switching occur throughout the CMF.
Private properties (residential and business) are located away from the CMF as follows:
- East side: 160 ft. to 650 ft.
- West side: 395 ft. to 464 f
*As of December 31, 2019
CMF has two sand towers which are used to store and distribute sand to locomotives as needed. Sand is used to provide traction and prevent wheel slip when moving locomotives. We receive sand deliveries up to 6 times a year.

This video gives and overview of the sand delivery process and how our Sand Towers are used at the CMF.
Upgrading Our Fleet-Tier 4 Locomotives
Metrolink is transitioning primarily to a fleet of Tier 4 locomotives, with 40 units ordered. The state-of-the-art Tier 4 locomotives are the cleanest diesel locomotives in the nation, providing wide-ranging environmental benefits for our region. We anticipate all 40 units will be in service by summer 2020.
More information on Tier 4 locomotives can be found HERE: metrolinktrains.com/tier4.
Metrolink has a long history with the CMF community -- including residents, businesses, elected officials and other stakeholders in Cypress Park, Glassell Park and Elysian Valley. In the past eight years, Metrolink has made various operational enhancements and modifications to reduce negative impacts to the community including, but not limited to:

Health Risk Assessment
Sound Study - 2017
Metrolink’s Central Maintenance Facility (CMF) is located in one of eight parcels of land where a Southern Pacific Railroad service yard known as Taylor Yard once stood. Taylor Yard serviced locomotives and rail cars from the 1920s through the 1960s.It was one of the largest service yards in the Los Angeles area and was responsible for the maintenance of locomotives and rail cars. By the 1960s Taylor Yard had slowed down most of its operations and was completely closed in 1985.
Taylor Yard in 1962
The Southern California Regional Rail Authority (Metrolink) began CMF operations in 1991. Use of the facility was listed in a 1992 Memorandum of Understanding (MOU) with the City of Los Angeles and the Los Angeles County Transportation Commission (Metro). Metrolink operates seven routes through a six-county, 538 route-mile network. Metrolink’s passengers travel approximately 441 million miles each year, making Metrolink the second busiest public transportation provider in Southern California. Metrolink is the third commuter rail agency in the United States based on directional route miles and the eighth largest based on annual ridership. The CMF provides a critical function for Metrolink to provide this regional service.

Present day CMF facility
The Southern California Regional Rail Authority (Metrolink) is a joint powers authority governed by five county-level agencies: the Los Angeles County Metropolitan Transportation Authority, the Orange County Transportation Authority, the Riverside County Transportation Commission, the San Bernardino Associated Governments and the Ventura County Transportation Commission. Metrolink has five levels of oversight: Public, Member Agencies, Local, State and Federal. We are also overseen by eight regulatory agencies that can request an inspection at any given time.
