Tren del Valle is a 10 km (6.2 mi) commuter rail service that connects cities of Plottier, Neuquén and Cipolletti, in the Río Negro and Neuquén Provinces of Argentina, running on Roca Railway tracks. In a second stage, the line would be extended to General Roca and Plottier, in the same province. The Tren del Valle is named after "Alto valle del Río Negro", a valley located at the north west of Río Negro Province, crossing cities of General Roca, Cipolletti, Villa Regina, Cinco Saltos, among others. It extends from the confluence of Limay and Neuquén rivers to Chichinales. The region is about 52,000 m2 (560,000 sq ft) in size, and is also notable for its production of apples as well as its vast Vaca Muerta oil field, whose freight lines will share some tracks with the Tren del Valle. The service, after preliminary tests, was opened on 21 July 2015, being operated by state-owned Trenes Argentinos. From Wikipedia
