Peru evacuated some 1,400 tourists overnight from the train station that serves the Inca citadel of Machu Picchu, while about 900 others remained stranded as protesters blocked the railway tracks, officials said.
A UNESCO world heritage site since 1983, the ancient, fortified complex receives some 4,500 visitors on average each day, many of them foreigners, according to the Peru's tourism ministry.
Residents placed logs and rocks on the tracks yesterday to demand a new company be chosen to run the buses that ferry visitors from the Aguas Calientes train station, at the foot of Machu Picchu, to the site itself.
Visitors arrive at Aguas Calientes by train from the city of Cusco - the Inca empire's ancient capital - some 110 kilometers away.
The previous bus firm's contract had come to an end after 30 years, but it has continued to provide services much to the ire of residents, who demand a new company, responsive to their interests, be chosen in a fair bidding process.
"We managed to evacuate about 1,400 tourists" trapped at the train station in an overnight operation before a fresh blockade today, Tourism Minister Desilu Leon told RPP radio.
Authorities have not said where the visitors were from.
Ms Leon said a meeting was planned with local authorities and unions "to find a solution" to residents' complaints.
Machu Picchu was built in the 15th century at an altitude of 2,500 meters on orders from the Inca ruler Pachacutec.
It is considered a marvel of architecture and engineering, but has repeatedly been the scene of protests by locals pressing home their social demands.
In January last year, some 1,200 tourists had to be evacuated from Machu Picchu - some without even laying eyes on the site.
A year earlier, it was closed for 25 days during protests over the impeachment and arrest of then-president Pedro Castillo.
