Angels Flight: World's Shortest Railway
Los Angeles, California
California city, steep hills, mass transit on rails. San Francisco leaps to mind. But Los Angeles was the first Golden State metropolis to employ a hillside hauler.
The Angels Flight Railway opened on May 31, 1901, as a quick (50 seconds) way to get people 300 feet up a hill in downtown L.A. Progress made it obsolete in 1969, but usually careless Los Angeles cared too much for its "World's Shortest Railway" to let it die. It was dug up, put in storage for 27 years, then rebuilt and reopened a half-block south of its original site in 1996, with no pretense that it was anything other than a quirky tourist attraction.
That lasted until 2001, when a fatal accident shut down Angels Flight. Blame was eventually assigned, the guilty parts were re-engineered, and Angels Flight Railway went back into service in March 2010 -- until it fell off the tracks in 2013 and was shut down again. It reopened and returned to regular service on August 31, 2017.
