Peru occupies a vast territory and because the main mode of transportation is by plane. Flight Lima - Cusco takes 55 minutes. The railway connects the Sacred Valley of the Incas, Cuzco, Machu Picchu to Lake Titicaca, and Arequipa to Lake Titicaca. The train from Cusco to Puno (Titicaca Lake) is about 10 hours. Quite a popular bus service. Buses are comfortable, but the crossings are very long. For example, bus Lima - Puno takes about 42 hours. A small nuance: in Peru, often not followed the schedules of all modes of transport, so the transplant on a plane, planning trips by rail, etc. should be done with a stock over time.
