The NS 93 (Neumático Santiago 1993) represents the third generation of rubber-tyred metro trains operated by the Santiago Metro. Produced by Alstom from 1996 through 2002, these units began service in 1997. Although originally intended for Line 5, their initial deployment was on Line 2 prior to Line 5's inauguration; currently, they serve Lines 1 and 5.
Features
Drawing inspiration from the MP 89 model utilized in the Paris Métro, the NS 93 features tapered ends, automated doors, and inter-car gangways. It has a slightly increased height compared to the MP 89 to facilitate air conditioning installation. Train configurations differ depending on the line: Line 5 operates six-car sets (90 m) and seven-car sets (105 m), while Line 1 runs eight-car formations (120 m). Each individual car is approximately in length, with the driver cab cars being marginally longer.
The interior design showcases a cream-white palette complemented by orange plastic seats. Unlike the MP 89, the NS 93 is equipped with a train speed monitoring system known as SACEM. Automated audio announcements for stations were introduced in 2010. Since 2016, select trains have been fitted with CBTC technology to enhance service frequency on Line 1.
