Financial problems forced the sale of the company to the Argentine government in 1909.

The company was founded in 1889 to take over a concession, originally granted to Otto Bemberg & Co. the previous year, for the construction of a metre gauge line, 152 km long, from the Córdoba to Cruz del Eje via La Calera and Cosquín following the River Primero.

The section from Córdoba to La Calera was opened on 30 July 1891 and San Roque was reached later that year on 4 September.

In 1895, the company owned 8 locomotives, 12 coaches, 4 brake vans, 87 goods wagons.
