The NS 93 (Neumático Santiago 1993) is the third generation of rubber tired rolling stock used on the Santiago Metro system. The trains were manufactured by GEC Alsthom in 1996 and went into operation in 1997. Originally designed for use on Line 5, the trains first operated on Line 2 prior to the opening of Line 5, and today work on the lines 1 and 5.
Features
The NS 93 series is based on the design of MP 89 series from the Paris Métro, along with sloped ends, automatic doors and through gangways from car to car. However, the NS 93 is slightly taller than the MP 89 to accommodate air conditioning, and they operate in 6 car formations on Line 5 (SN-NP-NNS), 7 car formations on Lines 1 and 5 (SN-NP-NRNS), and 8 car formations on Line 1 (NNS-NRNS). As a result, the trains can operate in six-car 90-meter (295 ft 3 in), seven-car 105-meter (344 ft 6 in), and eight-car 120-meter (393 ft 8 in) lengths, depending which line they are assigned to. The length of each car is 14.88 meters (48 ft 10 in) (15.38 meters or 50 ft 6 in for cars containing the driver's cab).
The interior of the NS 93 has a cream white scheme with orange plastic seating. Each trainset is also equipped with a train speed surveillance system (SACEM), which the MP 89 does not have. In 2010, automated station announcements were added to all trains.

On February 7, 2012, a train en route to one of the garages derailed near a condominium complex and playground.
