Subte Linea A is considered the tourist epitome in every guidebook of Buenos Aires. I guess, back in the good old days when Argentina was unimaginably rich this was one of the most comfortable and elegant public transportation lines in the world. This picture shows some details of the historical wooden interior of Linea A which is in use since the Roaring Twenties. Nowadays, riding this subway line isn't so pleasant anymore. It is making a loud clattering sound when running, but still, it's fun. It is definitely one of the most authentic tourist attractions in Buenos Aires.
