Rolling Stock
The Santiago Metro currently operate 6 models of rolling stock, one model (the AS 02) is steel-wheeled, while the others are all rubber-tyred. The NS 74 and NS 93 stock are based off the MP 73 and MP 89 stock of the Paris Metro respectively. All rubber-tyred stock are preceded with the acronym NS (for Neumático Santiago). The number reprsenting each type of rubber-tyred and steel-wheeled rolling stock is the year of design of a particular rolling stock, not year of first use, similar to the practice in the Mexico City Metro and Paris Métro. Also, all train types use forced-air circulation as they are not fitted with air-conditioning, unlike in many other metro systems.
In September 2012, the NS 2012 trains went into service on Line 1. These trains are the first to have air conditioning .

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)
“I’d rather I were dead and gone,
And my body laid in grave,
Ere a rusty stock o coal-black smith
My maidenhead should have.”
—Unknown. The Twa Magicians (l. 17–20)
