| Particularities: | |
The Z 8100 series (name of the SNCF ), or MI 79 (name of the RATP ), are electric multiple units that were developed for line B of the RER in Île-de-France . The units were the first two-system multiple units that could run on both the RATP and SNCF routes in Île-de-France. The derived series Z 8400 or MI 84 was for the RER A developed.
As a rule, the railcars run as a double unit , and trains from both series can be coupled. Such a train offers space for up to 1700 passengers.
Vehicle concept
The units of the Z 8100 series should be able to run both on the RATP routes south of Paris and on those of the SNCF north. The most important differences were the different platform heights (elevated platforms in the south and low platforms in the north) and the different power systems (1.5 kV direct voltage in the area of the RATP and 25 kV alternating voltage in the area of the SNCF).
A multiple unit consists of four cars:
- a ZBD 8100 railcar,
- an intermediate car ZRAB 28100 (formerly first class),
- one intermediate car ZRB 28100,
- a ZBD 8100 railcar.
Z 8400 / MI 84
The MI 84 and MI 79 are very similar and can also be coupled to one another. However, they differ from one another in some details. The maximum speed of the MI 84 is limited to 120 km / h instead of 140 km / h and its displays for the train names are smaller. In the interior, the MI 79 has luggage racks and walk-in inter-car transitions, the MI 84 does not.
They also differ in their power electronics : the chopper of the MI 79 is air-cooled, while the MI 84 uses coolant. The control electronics of the MI 79 are analog , the MI 84 uses microprocessors.
Construction series
The vehicles of the Z 8100 series were built in two series: The first series from 1979, called MI 79 A , consisted of 82 trains, which were procured by the RATP (31 trains) and the SNCF (51 trains). That same year, the RATP procured a second series of 38 trains, MI 79 B .
The units of the Z 8400 series were purchased in 1984 in a series of 73 vehicles, all of which belong to the RATP.
commitment
Z 8100 - MI 79
All trains of the Z 8100 series (trains of the SNCF, these are based in Mitry-Claye) or MI 79 (trains of the RATP, these are assigned to the Massy depot) are used on the RER B. They are all serviced at the RATP's Massy-Palaiseau plant.
In the harsh winters of 1985, 1986 and 1987, the Z 8100 series was very sensitive to frost, which led to numerous problems and train failures. To compensate for these failures, the 50-year-old type Z trains had to be reactivated. These were only designed for the power system of the RATP, so that the interconnexion (connecting the trains at the Gare du Nord ) had to be abandoned. As a result, the insulation of the motors and electrical components was improved.
The trains Z 8244 (owned by SNCF) and Z 8269 (RATP) were destroyed in the attacks in the stations of Saint-Michel - Notre-Dame in July 1995 and Port-Royal in December 1996.
Z 8400 - MI 84
The 73 trains of the Z 8400 series (SNCF, based in Achères ) and MI 84 (RATP, assigned to the Torcy , Rueil-Malmaison , Sucy-en-Brie and Massy depots) are on lines A (39 trains) and B ( 34 trains) of the RER. The trains used on line B are also used in double traction with trains of the MI 79 type. The MI 84 are also all serviced by the RATP.
They have movable steps to take into account the numerous platform heights in their area of application. On the RER A, this function is now only required if the trains end in the event of operational disruptions at Saint-Lazare station, as the platforms along the route have been brought to a uniform height.
The Syndicat des transports d'Île-de-France (STIF) has announced that the MI 84 will no longer be used on the RER A from the end of 2014, where it will be replaced by the MI 09 trains. The vehicles that will become available will be used on the navettes (shuttle trains) between Melun and Montreau on the R line of the Transilien and between Juvisy-sur-Orge and Melun (via Évry-Courcouronnes) on the RER D , where they will replace the Z 5300 .
modernization
First modernization of MI 79
The MI 79 used on the RER B received new passenger information systems in 2007. This included destination displays made of light-emitting diodes, which alternately show the train name and destination, as well as automatic stop announcements.
Second modernization of MI 79
In October 2007 Alstom was commissioned by RATP and SNCF to plan a modernization of the interior of the 119 MI 79. After a prototype that was manufactured at Alstom in Reichshoffen , the first renovation of a train followed in the RATP works in Sucy-en-Brie . The first renovated multiple unit was used on December 7, 2010.
This extensive modernization of 119 trains cost 317 million euros, half of the region were worn Ile-de-France. The technology was modernized and the internal and external appearance changed. In the interior, cooled ventilation (but no air conditioning), video surveillance and an improved passenger information system were introduced. The color scheme in the passenger compartment was lighter, and the outside of the trains was painted in the colors of STIF.
Six MI 84 trains used on the RER A are to be used on the RER B as part of the RER B North + program . These trains will undergo the same modernization, the costs for this amount to 1.7 million euros. To compensate, 11 additional trains of the type MS 61 are to be upgraded for further use on the RER A.
In September 2011, a study found asbestos residues in the newly renovated trains. Of 60 vehicles examined, asbestos was found in 32 (according to RATP) to 36 (according to their employees). The affected trains were taken out of service and cleaned of the asbestos. Drivers and maintenance staff were concerned for their health and carried out a surprise strike on the evening of October 26, 2011.
