MF 67


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 fifteen Métro lines : the MF 67 also operated on Lines 7, 8 and 13, 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 new trains provisionally known as 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.
Currently, the RATP uses a string of MF-67 "Auteuil Convoy" trains, to supply the Auteuil and Vaugirard Depots, these trains are colored yellow and brown and serve as auxiliary equipment of the work of the RATP. They replaced the aging tractor variants of the Sprague-Thomson.
