Map showing the new alignment of the T Third to Chinatown-Rose Pak Station, connecting from 4th and King streets and continuing north to Central Subway; existing Muni Metro system's J Church, K Ingleside and M Ocean terminating at Embarcadero Station; the N Judah continuing along the Embarcadero to Caltrain at 4th and King streets.

New T Third service via Central Subway starts January 7 with service between Sunnydale and Chinatown-Rose Pak Station.

On Saturday, January 7, the T Third starts its historic new route, providing a direct Metro connection between Sunnydale and Chinatown-Rose Pak Station. Service runs Mondays through Fridays, 6 a.m. to midnight every 10 minutes and Saturdays and Sundays, 8 a.m. to midnight every 12 minutes. The new T Third line vastly improves transportation to and from some of San Francisco’s most densely populated areas and major shopping corridors, expanding transit options and new connections.

The new T Third route will travel north to the new Central Subway from 4th & King platform. It will no longer turn onto King Street or run along the Embarcadero and the Market Street subway. Also, the K Ingleside will now travel between Balboa Park and Embarcadero Station.

New Connections

Customers traveling to stops along the Embarcadero, the baseball stadium at 2nd and King streets should transfer to the N Judah. Customers should transfer at Powell Station to Union Square/Market Street Station for the T Third going to Sunnydale.

To transfer to the new T Third at Union Square/Market Street Station from the J Church, K Ingleside, M Ocean View, N Judah or BART at Powell Station, you can connect entirely underground. From the Powell Station platforms, take the elevator or follow signs to concourse level, then follow signs to Union Square/Market Street Station.  

Customers on the T Third connecting to other Muni Metro routes or BART should follow signs on the Union Square/Market Street Station platform toward Stockton/Ellis streets.

Navigating the Union Square/Market Street Station

The new Central Subway stations have many new features, including long escalators – the longest in the United States west of the Mississippi – and two glass elevators at every level for more accessibility.

Customers who need to use the elevators to the platform should bypass the fare gates near the street entrances at Union Square/Market Street Station. Instead, use the fare gates in the center of the concourse.

MuniMobile and Lifeline customers may use any fare gate at the Union Square/Market Street Station.

Special Chase Center Event Service

During events at Chase Center, the SFMTA will run special event service about every 10 minutes in addition to normal T Third service. The additional special event trains – with “S Shuttle Mission Bay” head signs – will serve all stops between Chinatown-Rose Pak Station and UCSF/Chase Center. From end to end the ride takes only 20 minutes. Best of all, your event ticket is your Muni fare. No additional Muni fare needed!

Customers traveling past Chase Center during this special event service should check train head signs and only board “T Third” trains for a one-seat ride to their destination.
