Millbrae station is an intermodal transit station serving Bay Area Rapid Transit (BART) and Caltrain, located in Millbrae, California. The station is the terminal station for BART on the San Francisco Peninsula, served by two lines: The Richmond–Millbrae+SFO line on weekdays and Saturdays before 9 pm, and the Antioch–SFO+Millbrae line evenings and Sundays. It is served by all Caltrain service. The station is also served by SamTrans bus service, and Caltrain shuttle buses, and other shuttles.

Rail service to the area began with 17 Mile House station, which opened in 1864 on land deeded by Darius Ogden Mills; it was renamed Millbrae the next year. The station was rebuilt in 1890 and 1907 after twice burning down. The 1907-built station was threatened with demolition in 1976, but was added to the National Register of Historic Places in 1978. A modern intermodal terminal opened in 2002, connecting BART and Caltrain for the first time. The older station building was restored for use as a railway museum, which opened in 2004.

Millbrae station has five tracks and three platforms at ground level, with a fare concourse on a mezzanine level above. The Caltrain tracks are on the west side of the station. The westernmost (southbound) track has a side platform; the northbound track uses half of an island platform shared with BART. South of the Millbrae Avenue bridge, the northbound track splits in two to form a triple-track section to allow passing trains. The northbound platform extends past the BART area as a side platform, and curves to serve the diverging track.[2]

BART has three tracks; the western track serves the east side of the northbound Caltrain platform (with faregates between the two systems), allowing a cross-platform connection between northbound service. The other two tracks serve an island platform. Because ridership at Millbrae is lower than expected, only the western track is used in regular service; the other two tracks are used for train storage.[6]

A 2,200-space parking garage (with direct access to the mezzanine), busway, and surface parking lots are located on the east side of the station. A smaller busway and parking lot for Caltrain are on the west side.[7]

The BART platform at Millbrae has six sculptures partially embedded in concrete blocks, with each figure representing a different era in community history.[8] Forty-two terrazzo benches installed at the station show scenes of local nature and history.[9][10]

In 1862, after buying a section of Rancho Buri Buri from José de la Cruz Sánchez, Darius Ogden Mills deeded land to the under-construction San Francisco and San Jose Railroad in exchange for a station to allow guests to visit his estate. The line opened in October 1863; the adobe 17 Mile House station opened in 1864 and was renamed Millbrae the next year.[2][3] The line was soon taken over by the Southern Pacific Railroad (SP) for its Peninsula Commute service. The station burned in 1890.[2]

The station burned again in 1906 and was replaced with a two-story colonnade-style depot of standard SP design the next year.[11][12] It was located on the west side of the tracks just south of Millbrae Avenue. In 1976, preparing to discontinue the money-losing Peninsula Commute (which instead became publicly funded as Caltrain), the SP proposed to tear down the station.[2][13] However, it was added to the National Register of Historic Places as the Southern Pacific Depot on September 1, 1978 after efforts by the newly formed Millbrae Historical Society.[12] In August 1980, the building was moved 200 feet (61 m) south to make room for a widening of Millbrae Avenue.[2][13]

As part of the BART SFO Extension, a new intermodal terminal for BART, Caltrain, and Samtrans was built in Millbrae just north of Millbrae Avenue. BART service to the $70 million facility began on June 22, 2003.[14][2] The station was initially served by the Pittsburg/Bay Point line, plus a shuttle service to San Francisco International Airport station (SFIA).[15][16] The shuttle service was discontinued on February 9, 2004. The Richmond line began serving Millbrae at weekday peak hours, with the Pittsburg/Bay Point line providing service at other times.[17]

BART service to stations in San Mateo County is funded by SamTrans, rather than county tax revenues. As ridership stayed below expectations, SamTrans had to pay a larger-than-planned operating subsidy to BART. On September 12, 2005, in order to lower these subsidies, BART reduced service so that only the Dublin/Pleasanton line served SFIA and Millbrae stations.[18] SamTrans and BART reached an agreement in February 2007 in which SamTrans would transfer control and financial responsibility of the SFO/Millbrae extension to BART, in return for BART receiving additional fixed funding from SamTrans and other sources.[19]

On January 1, 2008, BART increased service to the San Mateo stations. Service to Millbrae station was provided by the Richmond line on weekdays, and the Dublin/Pleasanton line on weeknights and weekends. Direct service between SFIA and Millbrae was discontinued.[20] On September 14, 2009, the Pittsburg/Bay Point line was extended to Millbrae on nights and weekends (with the Dublin/Pleasanton line cut back to Daly City station), restoring direct service at those times.[21] Millbrae station was expected to have some 16,500 daily BART boardings by 2017, but has consistently fallen well short of projections, with under 7,000 daily boardings by then.[22]

On February 11, 2019, SFO–Millbrae line service resumed on weekdays and Sundays. The station continues to be served by the Richmond line on weekdays, with the Antioch line (formerly the Pittsburg/Bay Point line) serving both SFIA and Millbrae on weeknights and Saturdays.[23] On February 10, 2020, the SFO–Millbrae line began running during all operating hours, with the Antioch line operating only to SFIA.[24] SFO–Millbrae service ended on August 2, 2021; it was replaced by an extension of the Richmond line to SFIA weekdays and Saturdays, and an extension of the Antioch line to Millbrae evenings and Sundays.[25]

Caltrain no longer needed the historic station building after operations moved to the modern station. The Millbrae Historical Society negotiated with Caltrain to use the building as a museum in exchange for maintaining it. The Millbrae Train Museum opened in October 2004.[13] In 2006, Pullman car Civic Center, built in 1941 for the City of San Francisco, was moved adjacent to the station and opened as an exhibit.[26][27] The Society plans to acquire a locomotive and construct a section of track to run excursion service.[26][13]


Millbrae is planned to be a California High-Speed Rail station. Senate Bill 1029, passed in 2012, provided funds to lengthen the Caltrain platforms for future high-speed rail trains.[28] The station is to be expanded to accommodate the service.[29]

Millbrae station is served by a number of bus routes and shuttles:[7]

A large busway is located on the east side of the station. It is used by the Burlingame-Bayside Shuttle, Foster City Shuttle, SamTrans routes 397 and 713, the Sierra Point Shuttle, and private shuttles serving Genentech's South San Francisco campus and various airport hotels. A smaller busway adjacent to the southbound Caltrain platform is used by the Burlingame-North Shuttle, Broadway Millbrae Shuttle, and SamTrans route SFO. SamTrans route ECR stops on El Camino Real to the west of the station.[7]
