The MF 77 (French: Métro Fer appel d'offres de 1977; English: Steel-wheeled metro ordered in 1977) is a steel-wheeled subway train 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 suburbs of Paris, and as a result has a maximum speed of 100 km/h (62 mph) which - apart for suburban sections in le Kremlin-Bicêtre, Clichy and Saint Denis - wasn't fully utilized. In addition, it sports a new, curved silhouette with a wider midsection. Its original exterior colors, white and blue, led passengers to refer to it as le métro blanc, or white metro, as opposed to the mainly blue trains of the other rolling stock liveries.
Brand new MF 19 trains are set to replace the MF 77 between 2027-2036: first on Line 13 in 2027, then on Line 8 in 2029, and lastly on Line 7 in 2033. Once the MF 77 is retired, the entire Parisian subway network will be composed of trains with open gangways, automated announcements and asynchronous motors.
