Input: Question: What are the five other Muni Metro Lines that are shared at the Market Street Subway? Passage:The line runs from the Caltrain depot in the Mission Bay district to Ocean Beach and the Great Highway in the Sunset District. From the Caltrain depot at Fourth and King Streets, it runs along King Street and the Embarcadero, passing by Oracle Park. It then enters the Market Street Subway, which it shares with the five other Muni Metro lines. It exits the tunnel at Church Street and, after a brief stretch along Duboce Avenue to Duboce Park, enters the older Sunset Tunnel. This tunnel serves to avoid a hill and contains no underground stations. From the western end of the tunnel, the route goes along Carl Street, past UCSF-Parnassus Campus, on Irving Street, until it turns onto 9th Avenue for one block and reaches Judah Street, which the N runs on for the rest of its route. On Judah between 9th Avenue and 19th Avenue the N runs on a right-of-way that is slightly raised above the surrounding street. There is a loop in the intersection at Judah, La Playa and Great Highway that the N uses to turn around.
