The '''MF 88''' ({{lang-fr|'''M'''étro '''F'''er appel d'offres de 19'''88'''}}; {{lang-en|Steel-wheeled metro ordered in 1988}}) is a steel-wheel variant of [[electric multiple unit]]s used on [[Paris]]'s [[Paris Métro|Métro]] system. [[Régie Autonome des Transports Parisiens|RATP]] contracted a consortium of manufacturers, with [[Ateliers du Nord de la France]] (now [[Bombardier Transportation]]) in charge of the project. They were built following successful tests of a [[prototype]] train-set called the "BOA", derived from the [[MF 77]], which tested new features such as [[open gangway]] connections between cars to improve passenger distribution and special [[bogie]]s to reduce [[friction]] caused by the sharp curves found in the Métro network. It is planned for the [[MF 19]] rolling stock to replace the MF 88 in 2025. |
|||
== Design == |
|||
Carrying on the features of the BOA, a total of nine MF 88 train-sets were built, which have only ever operated on [[Paris Métro Line 7bis|Line 7bis]] in a three-car formation. It was the first model with AC motors as opposed to DC and with interconnecting gangways. It was also the last model not newly built with automatic announcements and with user-activated doors (all subsequent models, as well as more recently the MF 77s on Line 13, have had all doors open at once). The high rate of wear-and-tear of the train-sets has made maintenance much more expensive than expected. This is because of the design flaw in the [[chassis]], each bogie only has one [[axle]], similar to a typical car, bus, some [[Rubber-tyred metro|rubber-tyred trains]] (although the rubber-tyred lines of the Paris Métro use the typical 2-axle bogies), or certain [[Railbus|railbuses]], but unusual for a more “standard” railcar, especially one powered by electricity, |

== Formations == |
|||
As of 1 September 2022, eight MF 88 trainsets were in service and were formed as shown below. One trainset was scrapped in 2013. |
|||
As of 1 March 2022, eight trainsets were allocated to Pré Saint-Gervais Depot (Paris) for use on Line 7bis in a 3-car formation (two motor cars, one trailer). |
