New T Third Service Frequently Asked Questions
Q: How is service changing on January 7?
A: On January 7, 2023, the new T Third route will start with service from Chinatown-Rose Pak to Sunnydale via Central Subway. The T Third will continue north at 4th and King streets and connect to the new Central Subway stations instead of turning onto King Street and running along the Embarcadero and the Market Street subway.
The K Ingleside will no longer be combined with the T Third but will continue its regular route between Balboa Park and Embarcadero Station. Customers traveling to stops along the Embarcadero, the baseball stadium at 2nd and King streets and Caltrain should transfer to the N Judah. Customers going to Sunnydale should transfer at Powell Station to Union Square/Market Street Station for the T Third.
Special weekend service during November and December 2022 gave customers a chance to preview the new stations ahead of the January 7 permanent service change.
New Connections and Wayfinding
To get to Chinatown: If you’re already on the T Third, stay on! If you’re on another Metro route or BART, transfer at Powell Station. Go up to the concourse level and exit the fare gates but stay inside the station and follow signs and Ambassadors toward “Central Subway” to the Union Square/Market Street Station. At Union Square/Market Street Station, board T Third trains northbound to Chinatown-Rose Pak Station.
To get to 4th & King (Caltrain):
- Starting January 7, 2023, the new T Third will run between Sunnydale and Chinatown and continue to serve 4th & King.
- The N Judah will also continue to serve 4th & King next to the Caltrain depot.
- The K Ingleside will run between Balboa Park and Embarcadero Station. Customers will need to transfer to the T Third or N Judah.
To get to UCSF/Chase Center, Mission Bay, Potrero, Bayview, Visitacion Valley and Sunnydale: Use the new T Third between Sunnydale and Chinatown-Rose Pak Station. J Church, K Ingleside, L Taraval Bus, M Ocean View and N Judah customers should transfer from Powell Station to the new T Third at Union Square/Market Street Station.
Special event shuttles will run along the new T Third route as additional service during events at Chase Center. Trains will be marked S Shuttle Mission Bay. Customers traveling past Chase Center should check the train head sign to be sure it says “T Third.”
To get the BART from the new T Third: To connect to BART from the new T Third line via Central Subway, get off at Union Square/Market Street Station and walk underground to Powell Station, which is served by both Muni and BART.
To get to stops along the Embarcadero (at Folsom and Brannan streets) and 2nd & King (Oracle Park): The N Judah will continue to serve these stops. T Third customers should transfer at Union Square/Market Street Station to Powell Station. All other Metro customers should catch the N Judah at any Market Street Subway stop between Van Ness and Embarcadero stations.
To get to other regional transit like SamTrans and AC Transit: The best option is to connect at the Salesforce Transit Center on Beale Street between Mission and Howard streets, approximately a block south of Embarcadero Station. From the new T Third line via Central Subway, transfer at Union Square/Market Street Station to Powell Station and take any Muni Metro route to Embarcadero station. All other Metro routes will continue to serve Embarcadero Station.
Q: How long do customers have to make a transfer before being charged again?
A: 2 hours. Plenty of time to navigate between Powell Station and Union Square/Market Street Station! But note that during special weekend service, rides in Central Subway are free. Starting January 7 customers will need to tag into the fare gates.
Q: What’s the best way to connect to Powell Station from Union Square/Market Street Station?
A: If you are accessing Union Square/Market Street Station on Muni, exit the train and look for signage on the platform toward Ellis Street. Go up to the concourse level and look for additional signage toward Powell Station, J, K, N, M.
Q: How do I know which side of the platform to board at Chinatown-Rose Pak Station?
A: Trains may enter and exit from both sides of the platform at Chinatown-Rose Pak Station. Displays will show train departure times. This is different from other Muni Metro stations. Customers should look at the displays on either side to see which train will depart soonest and listen for audio announcements.
In Union Square/Market Street Station and Yerba Buena/Moscone Station, signs indicate the direction and destination of the trains on either side of the platform, such as “Southbound, Sunnydale” and “Northbound, Chinatown.”
Q: The stairs and escalators are long! Is there an alternative?
The new Central Subway stations are very deep! They have some of the longest stairways in the country. The stairs and escalators can feel daunting for some. Please hold on to the railings when using the stairs, take your time and move safely. Remember to stand to the right and walk on the left on the escalators.
Elevators are also an option, especially for customers with strollers, luggage or groceries. In Chinatown-Rose Pak Station, the elevators from the concourse to street level are located near the ticket machines. In Yerba Buena/Moscone Station the concourse to street elevators are located to the right when exiting the fate gates. In Union Square/Market Street Station the concourse to street elevators are in the middle of the concourse with a dedicated fare gate.
We will also be adding multilingual and accessible labels to the elevator buttons in all the stations.
Q: How do I get to Caltrain from West Portal?
A: Take any Metro route eastbound at West Portal, exit at Powell Station, transfer underground to the new Central Subway Union Square/Market Street Station and take the T Third southbound four stops to 4th & King.
Alternately, take any Metro route eastbound at West Portal to Powell Station. Exit at Powell Station to street level, walk east to 4th and Market streets (about four minutes) and catch the 30 Stockton or 45 Union/Stockton in front of Trader Joe’s on 4th Street.
Q: How do the rail changes affect my bus route?
A: The T Third Bus will now serve Chinatown, running along 3rd and 4th Streets in SoMa and on Stockton Street north of Market Street to align with the new T Third rail line and will no longer travel on the Embarcadero and Market Street. Otherwise, the change in Muni Metro service does not affect any other Muni bus routes. However, the new T Third provides a new alternative to multiple bus routes that also serve the SoMa/Union Square/Chinatown areas. These include the 8 Bayshore, 8AX Bayshore Express A, 8 BX Bayshore Express B, 15 Bayview Hunter’s Point Express, 30 Stockton and 45 Union/Stockton.
Q: How will the new T Third affect service in Bayview?
A: Many Muni routes will continue to serve the Bayview, Dogpatch, Visitacion Valley neighboring areas, including the T Third, 8 Bayshore, 8AX Bayshore Express A, 8BX Bayshore Express B, and 15 Bayview Hunters Point Express. Starting January 7, the T Third Metro line will run between Sunnydale and Chinatown via Central Subway, providing a more direct trip with fewer stops to SoMa, Union Square and Chinatown, and it will continue to serve Chase Center.
At 4th and King streets the T Third will continue northbound and will no longer run along King Street, the Embarcadero or the Market Street subway tunnel. For service to Oracle Park, the Embarcadero and the Market Street subway, customers can transfer to the N Judah at Powell, Embarcadero or 4th and King streets near Caltrain.
To connect to BART from the new T Third line via Central Subway, riders should get off at Union Square/Market Street Station and walk underground to Powell Station, which is served by both Muni and BART.
