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.
In the early 1970s, upon the completion of the MF 67 delivery, at the time the newest steel-wheeled trains on the Métro, many technological advances in braking and traction caused the RATP, which oversees operations of the Parisian public transport network, to examine the possibilities for new steel, rather than rubber, wheeled trains to replace the aging Sprague-Thomson fleet. Thus, the RATP commissioned a consortium of companies including Alstom, CEM, Creusot-Loire, and Jeumont Schneider, to design a new addition to the Métro's rolling stock, the MF 77.
The RATP's goal at the time of commission was for 1,000 cars, 600 of which to contain engines for 200 five-car sets. Later, the order was reduced to 187 sets for a total for 935 cars. The first trains were delivered in the summer of 1978 and entered passenger service on 26 September that year on Line 13, whose MF 67 trains were transferred to Line 8. A second order of ten sets was contracted on 4 February 1983, released in 1985 and 1986.
The trains on Line 13 recently underwent their mid-life refurbishment, which included a new interior configuration, updated destination signage, lighting and mechanical improvements. However, the RATP was largely dissatisfied with the refurbishment of the Line 13 trains, citing problems with the contractor that handled the work, as well as defects in the workmanship. Though it is expected that the trains on Line 8 will be refurbished next, followed by the trains on Line 7, the RATP will explore other avenues to carry out the work, even if it means that the refurbishment is done on a lesser scale (similar to that of the refurbishment of the MF 67 on Lines 10 and 12).[2]
As of January 2019, trains on the 7 and 8 are undergoing renovation, but on a lesser scale to that of trains on the 13.[3] While seating on board the trains are extremely similar, noticeable differences between the two projects include:
Additionally, renovated trains on the 7 and 8 will sport the new joint RATP/Île-de-France Mobilités (formerly known as STIF) blue/white livery.
