New Muni Line

Can anyone tell me about the new Muni light rail that is supposed to open about now ? I understand it operstes from the Caltrain station heading south. Does it go near Quint St. ? I intend to go there this summer and want to phptograph something going over the Quint St bridge. I saw an old SP unit on that bridge in a book and want to get something going over that bridge.

According to the MUNI website, the T/Third Street line opened on April 7. More here, including a map that should answer your questions:
