The MS Series 61 (MS stands for "Matériel suburbain" (local material) 61 for the start of development, 1961) referred to French electric railcars of Paris transport company RATP which for the line RER A of the train -like Paris train network Réseau express régional ( RER) and were ordered from 1963.
The companies Brissonneau et Lotz , Ateliers de construction du Nord de la France (ANF, now part of Bombardier ) and Compagnie industrial de matériel de transport (CIMT, now part of Alstom ) were responsible for the car bodies and assembly . Brissonneau et Lotz and the machine tool factory Oerlikon (WO) built the motors, WO also the reduction gears and the regulators of the resistance brakes . Frangeco supplied the bogies , the electrical equipment came from Matériel de traction électrique (MTE).
The delivery of the first trains to the RATP took place in February 1967. They were initially used on the Ligne de Sceaux , where on June 29, 1967 the first use in passenger service took place. From December 14, 1969, the MS 61 was transferred to the Paris – Boissy-Saint-Léger line (" Ligne de Vincennes ") - which had been extended underground to the Nation station - where it took the place of trains hauled by steam locomotives. This section of the Ligne de Vincennes became part of the RER line A in 1977. However, the MS 61 could not be used on the line A on the western sections to Poissy and Cergy-le-Haut operated by the SNCF , as these with 25 kV alternating voltage are electrified, but the MS 61 were only designed for a power supply with 1.5 kV DC voltage . The use of the MS 61 ended in April 2016.
Vehicle concept
The MS 61 is a series of electric multiple units designed for a power supply via overhead contact line with 1500 volts DC voltage. With this power system, the RATP lines in Île-de-France are electrified, but not the SNCF lines, which are also part of the RER. Pantographs are located on each powered car, directly above the driver's cab.
A train of this type consists of three cars with a total length of 73.22 meters: an M.15xxx multiple unit, an AB.18xxx sidecar (originally 1st and 2nd class ) and another M.15xxx multiple unit. Both railcars have driver's cabs and from the start only ran the 2nd class. Up to three MS 61 can run in multiple traction, they have Scharfenberg couplings . The trains have an empty weight of 148 tons.
The trains have a Jeumont-Heidmann control system in which a servo motor drives a camshaft . This system for vehicles powered by DC voltage was often used by the French and Belgian railway industries, including several series for the Paris Métro .
Despite their age, the MS 61 have an acceleration of 1 m / s² from 0 to 40 hm / h, just like the newer series MI 84 and MI 2N . The maximum permitted speed is 100 km / h, and during test drives the trains have reached up to 122 km / h. The compressed air brakes are supported by resistance brakes and develop a maximum braking force of 1.1 m / s². The braking distance is 72 meters at 100 km / h.
inner space
The passenger compartment of each car was divided into two halves by partition walls when delivered. This was supplemented in the sidecar by a door to separate first and second class. The first class was abolished around September 1999 and the partitions were removed when the vehicles were modernized, but these were partially retained in the railcars because cables run through them.
A train offers 200 normal seats and an additional 92 folding seats. A total of 629 passengers can be seated and standing, the latter occupied by 4 people per square meter, i.e. 1887 passengers in a triple traction.
Construction series
The MS 61 were built and delivered in six series: A, B, C, D, E et Ex. The different series can be distinguished by their front parts:
The A / B series trains have a three-part windshield with a flat central part, a train destination indicator above the windshield, a partially corrugated front and their wipers are fixed on top. The class A railcars differ from those of the B series in that they are specially equipped for traffic on the Ligne de Sceaux (including pantographs with narrower abrasive bars).
The C, D, E and Ex series, on the other hand, have a one-piece, curved windscreen, a train destination indicator behind the windscreen and windscreen wipers that are attached to the lower end of the windscreen. The series C / D on the one hand and E / Ex on the other hand differ in the attached RATP logos: The C / D carry the logo from 1960, the E / Ex the one from 1976.
The front section was uniformly changed when the trains were modernized. It is now flat like the windshield, the train destination indicator is behind the windshield and the windshield wipers are attached below. The taillights were designed as LED headlights .
A railcar (M.15096) from series C had the front of series A / B when it was repaired after an accident at Auber station in 1980. This peculiarity disappeared after the modernization.

Modernizations
The first modernization of the MS 61 took place from 1985 to 1992. This had become necessary because the trains suffered numerous disruptions due to their intensive use. In order to be able to compensate for the failures of the MS 61, initially 9, later up to twenty-four MI 79 were removed from the RER B and used on the RER A. With the delivery of the MI 84, enough trains were ready to replace the MS 61 that were missing during its modernization, so this could begin.
In the 1990s, three trains (M15067 - AB18048 - M15066, M15053 - AB18046 - M15054 and M15002 - AB18001 - M15007) were given an anti-graffiti paint job. This consisted of blue lines with red rectangles on a white background. These trains have not been recognizable since they were modernized; they have been painted in the usual paint scheme.
In the early 2000s, planning began for a second modernization of the MS 61. Originally 91 trains were to be renovated, the costs for this were estimated at 72 million euros. 30 of the trains were to be refurbished in the RATP factory in Sucy-en-Brie , and 60 more in the Ateliers de Construction du Center in Clermont-Ferrand . The train M15051 - AB18042 - M15094 (from the A / B series) was converted as a prototype of this modernization. This differed in a few points from the trains that were later modernized as standard: It did not have a passenger information system , the seats were only changed in individual cars (and were given a different color scheme), and the paintwork and front remained unchanged.
The train of the pilot series (M15127 - AB18068 - M15109) only differed in the paintwork of the front from the later renovated trains, this was later adapted. It was used for some time to train the train drivers before it was used again in passenger operations. The first renovated trains were put back into service in May 2006.
As part of the renovation, the trains received passenger information systems in the form of loudspeaker announcements and route maps, on which the position and route of the train were indicated by light-emitting diodes. Numerous parts were also renewed, including the seats, wiring, loudspeakers, the floor and the lighting. The windows have also been replaced and the positions of the windows that can be opened have been changed in order to achieve better air circulation. The driver's cab has also been modernized. Air conditioning was not installed as it was considered too costly in view of the expected remaining usage time.
In July 2007, STIF decided to modernize ten more MS 61s in order to replace six MI 84s that were to be used on the RER B in the future. The cost of renovating these additional trains was put at 12.25 million euros.
commitment
The first trains delivered were used from June 1967 on the Ligne de Sceaux , which connects Paris with the southern suburbs of Sceaux and Saint-Rémy-lès-Chevreuse . Two years later, the MS 61 was used for the first time on the Ligne de Vincennes , which connects Paris with Boissy-Saint-Léger in the east and whose terminus in Paris had just been relocated to the newly built Nation station. The last trains on the RER B were withdrawn in February 1983 and replaced there by the MI 79.
The Ligne de Vincennes later became part of the RER line A, on which the MS 61 continued to operate, especially on the connection from Boissy-Saint-Léger to Saint-Germain-en-Laye . In the event of operational disruptions, operations were also carried out on the Marne-la-Vallée - Chessy ↔ Rueil-Malmaison and La Défense ↔ Torcy connections. The trains are located in the Sucy-en-Brie and Rueil-Malmaison plants of the RATP.
The MS 61 were replaced by the new MI 09 series . April 16, 2016 was the last day of operation for the series. One train (M.15050-AB.18024-M.15015) has been kept in a museum by the RATP in Villeneuve-Saint-Georges since 2010 . It hadn't been modernized.
