The MP 89 (French: Métro Pneu appel d'offres de 1989; English: Rubber-tyred metro ordered in 1989) is a rubber tired variant of electric multiple units used on the Paris Métro. Designed by Roger Tallon, two types were built by Alstom for service on Lines 4 and 14, and began service on Line 6. The trains on Line 1 were moved to Line 4 between 2011 and 2013 to replace the older MP 59s, though only 48 trains are used for revenue service. The remaining four trains are stored either at Montrouge or Saint Ouen as operational spares.
