Well! Looks like I got lucky. The day after we returned from Machu Picchu and Aguas Caliente, the persistent rain caused a landslide that covered the railroad tracks, cutting off all travel to and from Machu Picchu. A landslide can be cleared off relatively quickly, in a matter of days. More importantly, the Urubamba River is going nuts, and threatens to erode the ground all along the tracks. If you’re coming to Cusco to see Machu Picchu soon, don’t. You won’t get there.
I thought the Urubamba was looking pretty angry, but I didn’t suspect it would have such impact. Here are a few pictures I took on the day before they closed the train down.
