The MF 77 (French: Métro Fer appel d'offres de 1977; English: Steel-wheeled metro ordered in 1977) is a steel-wheeled variant of the rolling stock used on the Paris Métro. First used in 1978, it now runs on Lines 7, 8, and 13.
Unlike previous models, the MF 77 was designed for travel into the immediate suburbs of Paris, and as a result has a maximum speed of 100 km/h (62 mph) which has yet to be fully utilized. In addition, it sports a new, curved silhouette with a wider midsection. Its original exterior colors, blue and white, led passengers to refer to it as le métro blanc, or white metro.
The MF77 trains are to be replaced between 2027-2036 by the MF 19 trains, first on Line 13 in 2027, then on Line 8 in 2029, and lastly on Line 7 in 2033. After the MF77 trains leave line 7, the entire network will be composed of trains with open gangways, automated announcements and asynchronous motors.
