What makes Cable Cars remarkable?
San Francisco's cable cars are the last manually operated cable car system in the world, designated a National Historic Landmark in 1964. Andrew Hallidie launched the first car down Clay Street in 1873, and the system once spanned 23 lines across 112 miles of track. Today three routes survive: the Powell-Hyde and Powell-Mason lines running from downtown to the waterfront, and the California Street line crossing Nob Hill. Each car weighs about 15,000 pounds and grips a continuously moving underground cable at 9.5 miles per hour. Over 7 million riders step aboard each year.
