The USC Libraries and KCETLink have partnered to create a series of videos drawing upon the collections of libraries, museums and private archives that make up the LA as Subject research group. The inaugural episodes, titled Incline LA, reveal the history of Angels Flight and other incline railways that once fulfilled an essential transportation function throughout Los Angeles. The first installment — covering the Angels Flight and Court Flight railways, or funiculars, in downtown LA — premieres today at 4:00 p.m. on KCET.org. Future episodes will tell the stories of Mount Washington, Catalina Island and Echo Mountain railways. Keep reading to learn more about the new collaboration.
