The MP59 Stock was ordered at the time that the RATP decided to convert Lines 1 and 4 to rubber tired operation. These were not the first "pneu" stock ordered, but they are currently the oldest "pneu" stock currently in service. They entered service in 1963 and currently operate on Line 11. They used to also operate on Line 1 and Line 4 but many have been retired as newer trains have been purchased and introduced in to service.
