Under what circumstances might there be a change from a direct train service to a combination of bus and train service between Cusco and Machu Picchu or vice versa?

In certain situations, and without prior notice, railway operators may opt for a combined BUS + TRAIN service instead of the regular direct train service between Cusco and Machu Picchu, as well as Machu Picchu to Cusco. This adjustment can arise due to unexpected rail maintenance, adverse weather conditions, or any other factors that could compromise the safety of passengers.

What happens if the rail segment between Cusco and Ollantaytambo, or Ollantaytambo to Cusco, is undergoing maintenance or temporarily closed?

If the railway section between Cusco and Ollantaytambo, or Ollantaytambo to Cusco, be undergoing maintenance or temporarily inaccessible for any reason, passengers will disembark at the Ollantaytambo station. The railway operator will then facilitate transportation from Ollantaytambo to Cusco by road, ensuring a seamless transition, all at no additional expense to passengers.
