[1] On November 15, 1915, it was promulgated the law that allowed the Executive Power of Tucumán (at the time, Governor Ernesto Padilla)[3][4] to create a freight and passenger rail line to connect San Miguel de Tucumán with the cities of Los Cuarteles, Villa Luján (también llamada Villa del Pueblo Nuevo), Villa Marcos Paz, Yerba Buena, and Parque Aconquija.

[5] The railway started at Plaza Alberdi (the square at the Central Argentine Railway station) and ran west on Calle Santiago del Estero, turned right into Avenida Mitre and followed it until they turned left into Avenida Manuel Belgrano.

On the Calle Aconquija (now Calle Luis Federico Nougués) it ran to the Avenida Mate de Luna, which it followed to the terminus Horco Molle at today's El Corte roundabout at the foot of the San Javier Hill.

[6] The locals preferred not to take the train because sparks from the locomotive often fell into the open carriages, damaging clothes.

Although a total of 135,505 passengers had been carried by 1925, the line closed in 1926 due to a lack of profitability.
