Buenos Aires Subway

Here is the Buenos Aires subway, Argentina.

The Buenos Aires was inaugurated in 1913, making it the oldest in South America and the southern hemisphere. It's called Subte in Argentina, short for Subterraneo. The Buenos Aires Metro had the oldest and among the most diverse rolling stock in the world, in part because the network was originally built and operated by three different companies, resulting in incompatibilities between lines.

The Belgian vehicles of La Brugeoise built around 1912 and put into service from 1913 to 1914 on the A line, renovated in 1926 were in service until 2013 (one century of exploitation!).

I wanted to do this metro because he has been one of the oldest metro which kept rolling and also because it has a pleasant old design.
