Interior of the MF 88.

The MF 88 is a steel-wheel variant of electric multiple units used on Paris's Métro system. RATP contracted a consortium of manufacturers together following successful tests of the BOA prototype, with Ateliers du Nord de la France (now Bombardier Transportation) in charge of the project. A total of nine train-sets are built, and currently operates on Line 7bis in three-car formation. The high rate of wear-and-tear of the train-sets made maintenance much more expensive than expected; it has been speculated that they would be likely to be replaced by spare MF 67s, which in turn are due to be replaced by the MF 2000.
