"...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 90-meter (295 ft), 105-meter (344 ft), and 120-meter (394 ft) lengths, depending which line they are assigned to. The length of each car is 14.88 meters (48.8 ft) (15.38 meters or 50.5 ft for cars containing the driver's cab).
The interior of the NS 93 is graced with 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."
