Dwight informed me that there is a great article in this month's Trains on Peru, Railroading in the Clouds. Here are a few pictures from last week of Peru Rail. Peru has duel gauges, most is, in Steve's terms, "Broad Gauge" or 4' 8 1/2". Some sections are 3', still "Broad Gauge" according to Steve. The 3' section from the ancient Inca capital, Cusco, which follows down along the Urubamba River to the Hidroelectrica power plant below Aguas Calientes is about 4,000 feet below Machu Picchu.
Below are pictures of one of the large 3 footer motive power as well as one across the Urubamba River below KM 104 where we departed the comfort of PeruRail to trek up the old Inca Trail past many ruins to the Sun Gate overlooking Machu Picchu.
