lighting were replaced with LED bulbs which increased visibility for operators and had a lower drain on the batteries. Network The current cable car network consists of three routes: The Powell–Mason (Line 59 or PM) line, follows a common route with the Powell–Hyde line, running north and steeply uphill from a terminal at Powell and Market Streets, before crossing the California Street line at the crest of the hill. Once California Street has been crossed, cars coast downhill, off the cable, for three and a half blocks until the lines split as they turn left onto Jackson Street (as this is one-way, cable cars in the opposite direction use the parallel Washington Street). The cars on this line turn right and downhill along Mason Street, briefly half left along Columbus Avenue, and then down Taylor Street to a terminal at Taylor and Bay. This terminus is two blocks south of Fisherman's Wharf and is the closest to Pier 39. As with the Powell–Hyde line, there are manually-powered turntables at each end to reverse the cars. The Powell–Mason line has been in operation since 1888. The Powell–Hyde (Line 60 or PH) line, follows a common route with the Powell–Mason line, running north and steeply uphill from a terminal at Powell and Market Streets, before crossing the California Street line at the crest of the hill. Once California Street has been crossed, cars coast downhill, off the cable, for three and a half blocks until the lines split as they turn left onto Jackson Street (as this is one-way, cable cars in the opposite direction use the parallel Washington Street). The cars on this line continue uphill on Jackson/Washington to a crest at Hyde Street. Here it turns right and steeply downhill (at 21%, the steepest grade in the cable car system) along Hyde Street, past the "crooked" Lombard Street to the Hyde and Beach terminal, which is adjacent to the waterfront at the San Francisco Maritime Museum and Ghirardelli Square. As with the Powell–Mason line, there are manually-powered turntables at each end to reverse the cars. The line was spliced together in 1957 using portions of the O'Farrell, Jones & Hyde line and the Washington–Jackson line. Because this line offers iconic views of Alcatraz Island, passes Lombard Street and terminates near popular tourist destinations, it is the most popular with tourists and often has long waits to board.
