Macri made a comment about how the city didn't need equipment over 100 years old. He would have been referring to the "A" line which has a lot of the original early 20th century coaches, amazing antiques that continue to work well. It's the oldest subway line in Latin America that has survived only through indifference. An enlightened government would value these trains and the mostly untouched stations. With some mechanical overhauling and restoration the original wooden trains could continue to operate with the potential of being a major tourist attraction like the St Charles St trolley line in New Orleans or the cable cars in San Francisco. This of course would be a plus as the line would remain a vital transportation link. Sadly Macri is not interested in this sort of thing. His attitude toward the Teatro Colon has been antagonistic so that should give you an idea of his cultural leanings. The irony is that scrapping the old trains and replacing them with more used castaways from Japan (like the miserable B line) or wherever would not be a real improvement and would lead to missing a business opportunity, i.e. the promotion of tourism by refurbishing one of BA's most important legacies.
