In Medellin, Colombia. The subway is connected to two systems of Sky carts (similar to ones used on ski resorts). That allows the "subway system" to reach hard terrain (mountains) and expensive terrain (need only to set large polls and stations). For residential areas with high land prices, this might seem as an excellent and cheap to implement public transport. (These are the same areas where cars are usually sitting in traffic jams). Does anyone have information if this model is working out for them ? Is it used somewhere else successfully ?
