Bus Yard at Muni Metro East
In 2017, the San Francisco Municipal Transportation Agency (SFMTA) launched the Building Progress Program, a $1.2 billion multi-year effort, to repair, renovate, and modernize the SFMTA’s aging facilities to keep the City moving.
Potrero Yard, located at Bryant and Mariposa streets, is the first Building Progress Program capital rebuild project. Construction for Potrero Yard is expected to begin in 2023.
While Potrero Yard and other Building Progress rebuild projects are under construction, the SFMTA needs to build a bus facility to maintain Muni bus service. The SFMTA will construct a bus yard on a vacant parcel adjacent to Muni Metro East (MME). In addition, the SFMTA will renovate the maintenance facility located at 1399 Marin Street to expand capacity for bus maintenance there.
After rebuilding bus yards across the City, the SFMTA will consider using this yard to expand MME rail operations.
Muni Metro East (MME)
Located at 601 25th St, MME is a 16.9-acre site owned by the SFMTA and located in the Dogpatch neighborhood. The rail yard stores approximately 100 light rail vehicles and contains 14 maintenance bays. MME opened in 2008.

Located at 1399 Marin St is a 3.2-acre maintenance yard located between the Dogpatch and Bayview neighborhoods. The facility is a Muni motor coach acceptance yard, rail track shop, and street car storage facility. 1399 Marin opened in 1998.

As part of the Building Progress Program, operations and maintenance activities at Muni Metro East and 1399 Marin will expand to continue Muni operations and maintenance during the rebuild of other bus yards.
Bus Yard at MME
Four acres of vacant land on the MME site will be used as a bus operations yard to support the following activities:
- Bus operations, operator check-in trailers, lockers, restrooms, and break space.
- Bus washing served by below-grade rainwater cistern, fare pull, and interior bus cleaning.
- Overhead trolley charging (in yard only) and parking for approximately 160 trolley buses.
- Accessing the improved street on Maryland Street from Cesar Chavez.
