Rail link between Cusco and new airport estimated to cost at least $1.146 billion

A proposed railway linking Cusco with its new international airport could cost at least $1.146 billion, according to technical studies prepared by South Korea and presented to Peru's government.

The planned line would cover 21.77 kilometers and connect three locations: Cusco, the town of Poroy and the airport being built at Chinchero in the Sacred Valley of the Incas. The route reflects the region's difficult terrain, with a 300-meter elevation difference across a mountainous landscape.

The design includes 6.4 kilometers at ground level, 5.4 kilometers on viaducts and 9.9 kilometers in tunnels. The studies say this arrangement would adapt the railway to its surroundings and reduce interference with the city.

The proposed system would use automated light electric trains with two cars and double tracks. Staff would remain on board to assist passengers and respond to emergencies. The plan also calls for the railway and airport stations to be integrated with the orderly development of nearby tourism, commercial, residential and service areas.

South Korea prepared the study through its official development assistance program after a formal request from Peru's Transport and Communications Ministry. The Korean ministry commissioned consultants DOHWA Engineering and Korean National Railway. The completed study will be handed to Peru as a donation.

The Chinchero airport, located 3,700 meters above sea level, is being developed as a major entry point for tourists traveling to Machu Picchu. South Korea manages the airport project, and Spain's Acciona recently won the contract to build its control tower.
