Peruvian authorities have reopened the train route to Machu Picchu, the Andean country's railway operator said on Wednesday, after an agreement was struck to end protests that had blocked access to the famed Incan site and stranded tourists.

PeruRail said in a statement a partial service had restarted on Wednesday and that a regular service would return on Thursday from the city of Cusco to Aguas Calientes near the archaeological site.

Protesters said they feared the new electronic ticket sales platform would hurt local businesses by shifting the administration of ticket sales to one private company authorized by the Ministry of Culture.

The two sides signed an agreement on Wednesday that will see a transition period to the new platform.

"We have to move forward to reactivate our economy," Peru's Minister of Culture, Leslie Urteaga, told a local radio station.
