The MP 55 was the first generation of the rubber tired variant of electric multiple units used on Paris's Métro system. The trains were manufactured by a consortium between Renault, Brissonneau et Lotz, and Alstom and operated on Line 11 from 1956 to 1999, when they were replaced by refurbished MP 59 stock from Line 4.
