The Angel's Flight Funicular Railway:
The High Window, Chapter 8 
I parked at the end of the street, where the funicular railway comes struggling up the yellow clay bank from Hill Street, and walked along Court Street to the Florence Apartments.

The two cable-cars of Angel's Flight, a funicular railway built in 1900, carried passengers from the intersection of Third and Hill Streets up the steep slope to Olive Street (not Court Street, as Chandler has it.)  The railway continued operation until 1969, when it was closed to make way for the urban renewal of Bunker Hill.  After many years of promised restoration, the City of Los Angeles finally reopened Angel's Flight in 1997
