MP 89

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 has begun 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.

The MP 89 contains many features that are equipped in both subclasses. These innovative features made the MP 89 the first of its kind on the Metro and allowed the RATP to continue to equip its lines with the modernized stock.

Among many features, the MP 89 is the first class of rolling stock to include the automatic opening and closing of doors. Instead of a passenger having to pull a lever or push a button to open the door in order to enter or exit the train, all of the doors on the platform side open and close automatically. This is due to the fact that the lines using this material are predominantly underground. This feature was carried on by the MF 2000 and MP 05 rolling stock.

The MP 89 is also equipped with an audio and visual automatic system (AVSA Annonces Visuelles et Sonores Automatiques) which automatically detects the positioning of the station platform (whether the platform is on the left, or on the right side of the train). This detection allows the automatic opening of the train doors on the appropriate side of the platform. The system also allows for the operation of automated station announcements. Instead of the conductor having to utilize the intercom to announce station names, the automated system does this automatically. On curved stations, this system is especially vital due to the gap between the train and the curved platform. Automated messages announce the presence of the curves.

For example; if an MP 89 CC train approaches the curved station of Barbès – Rochechouart on Line 4, there will be an automated announcement of the station name "Barbès – Rochechouart" just prior to the train entering the station. As the train approaches the platform and begins to slow down, a second station name announcement "Barbès – Rochechouart" is made. In the case that a platform is curved, a third announcement is made in French, English, and a third language (usually Spanish, German, or Italian) that alerts passengers to "Please mind the gap between the train and platform". The MP 89 CA does not utilize "mind the gap" announcements at the present time because none of the platforms on Line 14 are curved.

Another new feature of the MP 89 is the interconnecting gangways in between cars, which was previously achieved with the prototype BOA and later the MF 88. This is described further in the next section, because the type of gangway equipped differs between the CC (SIG-Hübner) and CA (Paulstra) versions. The gangways were subsequently improved and equipped the later MF 2000 and MP 05 stock trains. (from fr:MP 89).

The MP 89 CC is manually controlled by the driver and originally circulated on Line 1 from their inception in 1997 until February 2013, replacing the aging MP 59 during the course of 1997 and 2000. The first train (#01) was delivered to the RATP in 1995 and was originally without articulation. Interconnecting gangways would not be installed until the train went into passenger service in 1997. 52 6-car trains were ordered for Line 1.

From 2006 to 2007, an experimental program ran on selected train-sets on an LCD passenger information system (Dilidam). This system would later be adopted by the new MP 05 automated rolling stock that now operate on Line 1 (from fr:MP 89).
