the almost forgotten Court Flight funicular, Los Angeles
This was 180 ft (55 metres) long on a gradient of 42%.
"Most Angelenos are familiar with historic Angels Flight, the tiny incline railway that has whisked passengers from the Historic Core to the top of Bunker Hill for the better part of a century. It wasn't always the only game in town though—Los Angeles experienced a bit of a funicular fad in the early Twentieth Century. Just a few blocks down from Angels Flight, another incline railway ran successfully for almost 40 years: Court Flight brought passengers up and down an even steeper hill than Angels Flight, from 1905 until October 20, 1943, when it was destroyed in a fire. While Angels Flight thrived (off and on) over the decades, Court Flight became just a footnote in history."
