Ok I'll try and write in batches for this... We are on the train at the moment eavesdropping on someone else's tour guide. The train is very nice, it's the polar opposite of the hikers on the inca trail. The train runs along the valley between the mountains, alongside the river. The scenery is very beautiful. We are chugging along the line built in the 1920s, the weather is immaculate and we can't wait to get up there.
