The MF 67 is a fleet of steel-wheel electric multiple unit trains for the Paris Métro. The first MF 67 trains entered service on Line 3 in June 1968, and became one of the biggest orders for the Métro, with 1,482 cars constructed. The need to replace the Sprague-Thomson fleet, as well as increasing costs associated with the later-cancelled plan to introduce rubber-tyred trains on all Métro lines, were the main factors for the size of the order. At its peak, during the late-1980s and the early-1990s, the MF 67 operated on eight of the (then) fifteen Métro lines (Lines 2, 3 and 3bis, 5, 7bis, 9, 10 and 12): the MF 67 also operated on Lines 7, 8 and 13 (including the old Line 14), all before the introduction of the MF 77 in 1978. Many of the MF 67 trains have been removed from service: throughout 1994, the MF 88 displaced the MF 67 from Line 7bis, and from 2008 to 2016, the MF 01 replaced the MF 67 on Lines 2, 5, and 9. The MF 67 remains in service on Lines 3, 3bis, 10 and 12, where the Île-de-France Mobilités intends to replace the remaining MF 67 trains with the MF 19.

Conception

It was originally envisioned by the RATP to convert all Metro lines to rubber-tyred pneumatic operation. However, this plan was later abandoned due to high costs, which in turn, would have prolonged the service of the aging Sprague-Thomson trainsets to 80 years. Therefore, a new class of steel-wheel rolling stock was developed. During the development phase, the MF 67 was known as the MF 65.

Series

The MF 67 actually comprises seven different series; however, two series of these trains were prototypes.

Technical specifications

Service trains

Currently, the RATP uses a string of MF 67 "Auteuil Convoy" trains (retired MF 67C trainsets from Line 2 in four-car sets), to supply the Auteuil and Vaugirard Depots. These trains are colored yellow and brown, and serve as auxiliary equipment of the RATP (VMI). They replaced the aging Sprague-Thomson trains.

Former trainset

Before 1971

During the first few years of operation, the MF 67s (A and C) were "full grip". All cars were motorized to maintain efficient speed and acceleration against the MP 59 (with tires). The order of cars (not motorized) made it possible to create the MP67 D by withdrawing 2 motor cars and replacing them by two cars. All MF 67Ds were transformed into MF 67A or C.

Line 7Bis

Until 1994, with the arrival of the MF 88, line 7bis used MF 67E in a trainset of 4 cars. These trainsets arrived in 1981–82 from lines 8 and 13 (which received new MF 77), and left from the 7bis line in 1994 for line 10 (which reformed the old MA 51) Information:
