Rolling Stock
As of April 2012, 14 types of standard gauge rolling stock totalling a number of 355 trains running in 6-or 9-car formation are currently in use on the Mexico City Metro. Four manufacturers have provided rolling stock for the Mexico City Metro, namely the French Alsthom, Canadian Bombardier, Spanish CAF and Mexican Concarril (now Bombardier Transportation Mexico, in some train types with the help of Alsthom and/or Bombardier).
The maximum design speed limit is 80 km/h (50 mph) (average speed 35.5 km/h (22.1 mph)) for rubber-tyred rolling stock and 100 km/h (62 mph) (average speed 42.5 km/h (26.4 mph)) for steel-wheeled rolling stock. Unlike the rolling stock of other metro systems in the world, the trains do not utilise air-conditioning; instead forced-air ventilation is employed in all trains and the top portion of windows can be opened so that passenger comfort is ensured by the combination of these two types of ventilation. Like the rolling stock used in the Paris Métro, the numbering of the Mexico City Metro's rolling stock are specified by year of design (not year of first use).
In chronological order, the types of rubber-tyred rolling stock are: MP-68, NM-73A, NM-73B, NM-73C, NM-79, MP-82, NC-82, NM-83A, NM-83B, NE-92 and NM-02; and the types of steel-wheeled roling stock are: FM-86, FM-95A, FE-07 and FE-10.

Famous quotes containing the words rolling and/or stock:
“Look, we’re all the same; a man is a fourteen-room house—in the bedroom he’s asleep with his intelligent wife, in the living-room he’s rolling around with some bareass girl, in the library he’s paying his taxes, in the yard he’s raising tomatoes, and in the cellar he’s making a bomb to blow it all up.”
—Arthur Miller (b. 1915)
“A man acquainted with history may, in some respect, be said to have lived from the beginning of the world, and to have been making continual additions to his stock of knowledge in every century.”
—David Hume (1711–1776)
