LIMA, Dec 31 — A head-on collision between two trains on the line that services Peru’s Machu Picchu killed one person and injured at least 40 others, authorities said, updating an earlier toll.

The deceased was the conductor of one of the two trains, according to the prosecutor’s office in Cusco, the city closest to the famous Inca citadel.

Officials said they were working to identify the injured train passengers, many of them foreign visitors and most of them seriously hurt.

Videos sent by passengers to the RPP television channel showed injured victims lying next to the tracks with two damaged locomotives standing idle nearby.

A dozen ambulances and medical personnel were rushed to the site in a remote Andean area without direct road access.

Police wearing hardhats and neon-coloured jackets carried injured passengers on stretchers from the trains to receive treatment.

A Unesco World Heritage Site since 1983, the ancient fortified complex of Machu Picchu receives some 4,500 visitors on average each day, many of them foreigners, according to the tourism ministry.

Most tourists take a train and a bus to reach the historic site high in the Andes mountains.

Rail agency Ferrocarril Transandino said a train operated by PeruRail collided with another belonging to Inca Rail around lunchtime on the single track that links the town of Ollantaytambo with Machu Picchu.

The cause of the accident was not yet known.

In September, about 1,400 tourists were evacuated from the Aguas Calientes train station that serves Machu Picchu and 900 others were left stranded after protesters blocked the railway tracks with logs and rocks.

Locals were demanding a new bus company be chosen in a fair bidding process to ferry visitors to the foot of Machu Picchu, and have repeatedly protested to press their demands.

The Inca empire’s ancient capital Machu Picchu was built in the 15th century at an altitude of 2,500 metres on orders from the Inca ruler Pachacutec.

It is considered a marvel of architecture and engineering. — AFP
