It is also interesting to read about the cable cars of Chiatura, Georgia, a small mining town that produces manganese. As of 2013, 17 of the aging tramways were in service.
The segment from 7min to 14min talks about Medellín and shows videos of the escalators and cable cars.
Given budget and land scarcity Seattle could really use a cable way to connect downtown to Ballard, Queen Anne and other neighborhoods. Hopefully future transportation planners will consider cableways more seriously.
