There it is one of the subway of Mexico City. I have never been to Mexico, but I have an interest for subways transits all over the world and I started a series of different subway train which seemed to be original like this one. The first line of Mexico has been built in 1969. The first metro construction projects date back to the 1950s. The tram and bus networks were no longer sufficient to meet demand. The metro is operated by STC Metro (short for Sistema de Transporte Colectivo Metro). I choose to do this subway because he has an original design. There is a very interesting page about the Mexico City transit on Wikipedia. It's hard to define which type of subway are running, past and present. The model I choose to do is named NM-79 or NM-83A, but maybe I make a mistake... I don't know Mexico City.
