 Service runs from Jones Street and Jefferson Street in Fisherman's Wharf to near the N Judah's platform at Caltrain's King Street and 4th Street Station in the Mission Bay neighborhood – the last trains of the day run to near the adjacent T Third platform at 4th and Berry.Since there is no loop at the Caltrain station, only double-ended streetcars are able to operate on the line until a loop track is built.An extension of the E Embarcadero to Aquatic Park is planned but is currently not fully funded.
