There are two cable car lines that begin at the Powell/Market turntable. One called the Powell-Mason runs up over Nob Hill and down to Bay Street at Fisherman's Wharf. The second, the Powell-Hyde line runs over Nob and Russian Hills before ending at Aquatic Park near Ghirardelli Square. A third line, called the California, runs East-West and only crosses Powell; it runs from the Financial District, through Chinatown, over Nob Hill and stops at Van Ness Avenue - GH
