The Mount Lowe Railway was a feat of engineering when it was constructed in the late 19th century: the third in a series of scenic mountain railways in America, with a funicular system built by the man who designed San Francisco's cable cars. Learn about the technical workings of this incredible system in a hike along the railway's former route with the Arroyos & Foothills Conservancy and John Harrigan, an electrical engineer and the author of Mt. Lowe Power. The hike is demanding at points, about a mile each way with several high narrow steps near a sheer drop, and a scramble over rocks.
