MF77

thingiverse

The MF 77 is rolling stock on the Paris Metro. Since 1978, it has been equipping lines 7, 8, and 13. It's designed to operate long extensions in the suburbs with a more comfortable layout and a top speed of 100 km/h, which isn't actually exploited afterwards. It has a new aesthetic thanks to a curved shape, wider at the waist level; its original colors are royal blue on the front faces and roof, as well as white on its lateral faces. For this reason, it's initially nicknamed "white metro" by users before receiving the uniform coat of the metro materials, white and green jade, during the 1990s. At the beginning of the 1970s, when deliveries of MF 67 are ending, numerous technological progress, especially in traction/equipment braking equipment, push RATP to consider a new rolling stock project intended to replace the last Sprague-Thomson trains on the network. This new material must also serve lines recently extended towards the suburbs with long sections outdoors1. It's thus that RATP places an order in July 1975 for new trains called MF 77 with a consortium including the following industrialists: Alsthom and Franco-Belge: provision of coaches and general assembly; CEM Oerlikon: provision of motors; Creusot-Loire and ANF: provision of bogies; Jeumont-Schneider: provision of traction equipment. The order is for 1,000 cars, including 600 motorized to make up 200 five-car trains. Later, the order is reduced to 187 trains, or 935 cars. First trains are delivered in summer 1978 and the first MF 77 train enters passenger service on September 26, 1978, on line 13, while the total equipment of this line is only completed in 1979. The few remaining MF 67 E on line 13 are transferred to line 8. The MF 67 F from line 13 are transferred to line 7 and the last Sprague-Thomson disappears from line 8 in June 1980. After line 13, subsequent MF 77 trains start running on September 12, 1979, on line 7, then later on line 8 in June 1980. The rolling stock intended for long lines with extensions to the suburbs, including outdoor sections, are designed to run at a maximum speed of 100 km/h. They also offer numerous equipment allowing to improve performance and passenger comfort compared to previous versions of rolling stock.
