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 (S-N-NP-N-N-S), 7 car formations on Line 5 (S-N-NP-N-R-N-S), and 8 car formations on Line 1 (S-N-N-N-N-R-N-S). 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. Since 2016 some trains are equipped with CBTC for better frequency in Line 1.
