The Sarmiento Railway Line, a 150 years old metropolitan Line serving Buenos Aires City, was part of one of the most ambitious infrastructure projects in Argentina’s recent times. The growth of the city and the changed necessities required the tunnelling of this line.

Renovation as a consequence of city growth

The Sarmiento railway line was opened in 1857, as one of 7 metropolitan lines serving the city of Buenos Aires. The city growth during more than 150 years and its nowadays necessities generated the need to tunnel this line.
