With a strong focus on sustainability, the Southwestern Yard Maintenance Facility was built to efficiently service and repair light-rail vehicles (LRVs) for two Los Angeles County Metropolitan Transportation Authority (LACMTA) transit lines. The facility is part of the ongoing Crenshaw/LAX Transit Corridor project, which will connect downtown and the Westside region of Los Angeles with the South Bay region of Los Angeles County. The lines will serve an estimated 27,400 passengers daily by 2035.
Southwestern Yard is large enough to service and store 56 LRVs and could be expanded to accommodate 70. The facility has earned a Leadership in Energy and Environmental Design (LEED) Silver certification for its energy-efficient features, which include a water capture and reuse system for vehicle washing. This system and other water-saving fixtures reduce water consumption by 40%. Gannett Fleming designed the facility, including an outdoor test track, traction power substation, and overhead contact system (OCS), and provided construction administration services.
The facility features five maintenance bays, a two-level administration area, a small shops area, and a two-story parts storage system designed to be expandable. It is fully equipped to handle LRV service and inspection, motor and body repairs, painting, cleaning, and washing. Because of its location in a region at risk of seismic activity, the facility was developed in accordance with seismic design principles to prevent or reduce damage in the event of an earthquake.
The track configuration and site layout support safe LRV movement between functional facilities, storage sites, and mainline tracks. A 750-volt traction power substation and OCS provide electricity to the LRVs. The facility features on-site stormwater treatment to remove oil from runoff and prevent overloads on the municipal system.
- Five maintenance bays enable full inspection and repair of LACMTA LRVs.
- Parts storage system facilitates quick LRV repair and can be expanded if needed.
- 750-volt substation and OCS provide power to move LRVs throughout the facility.
- More than 20% of the construction materials consist of recycled content, reducing waste and energy consumption.
- Capture and reuse system for vehicle washing and high-efficiency plumbing fixtures reduce water usage by 40%.
- On-site stormwater treatment reduces runoff pollution and lessens burden on municipal system.
- Drought-tolerant landscape plantings eliminate the need for watering.
- Bicycle parking, designated parking for fuel-efficient and carpool/vanpool vehicles, and electric vehicle charging encourage the use of energy-saving transportation by employees.
