Good morning guys. Today I would like to suggest the RER A Line of the Paris commuter system, the busiest in all of France in terms of commuter core. LINE MAP A little history of the line: HISTORY : After many years of study, construction began on July 6, 1961 with the inauguration of line A on December 14, 1969 of the Nation - Boissy-Saint-Léger section. This section starts from a new underground station under Place Nation and uses the old Vincennes line to Boissy-Saint-Léger. The section of this old line from Boissy-Saint-Léger to Verneuil-l'Étang has fallen into disrepair. A few weeks later a second underground section was opened between Charles de Gaulle-Étoile and La Défense, extending east to a new underground station, Auber, on November 23, 1971. On October 1, 1972, it was extended from La Défense to the west using, from Nanterre, the old line from Paris to Saint-Germain-en-Laye from 1837, re-electrified by catenary at 1500 V DC. Finally, on December 9, 1977, the Auber-Nation section was opened, crossing the center of Paris underground, with the new Châtelet-Les Halles station where a large Metro-RER interchange was created, and Gare de Lyon, an underground complex under the station of the same name of great lines. Thus the two sections of line A were joined, completing the original layout. A few years later ramifications were added: - To the east to serve Marne-la-Vallée and the Disneyland Paris Park. In December 1980 the first section to Torcy (then Torcy-Marne-la-Vallée) was opened and in 1992 it was extended to Marne-la-Vallée serving the Disneyland Paris Park. An intermediate station was opened in this section in 1992, and it would not be until 2001 when the last new line A station, Val d'Europe, was opened. - To the west to serve Cergy and Poissy from the Nanterre-Préfecture station, the branches diverging to each of these communes to the west of Maisons-Laffitte. This branch was incorporated on May 29, 1988, one of the branches being extended to the new Cergy-Le Haut station in 1994. Line A is the suburban transport line with the highest density of rail traffic and the highest demand in the world excluding Japan. More than a million passengers are transported on weekdays. This influx has rapidly saturated the line, initially equipped with a BAL signaling system until the RATP delegated to SIEMENS the creation of a new signaling and driving aid system, SACEM, in operation in 1989. This has allowed the increase significantly the frequency at peak hours. The commissioning of the double-deck MI2N "Alteo" (Z20K) trains has made it possible to increase the capacity of the line. However, given the increase in demand, the construction of line E of the RER was justified, practically doubling line A. The hypothetical expansion project to the west would lighten line A and double the frequency of trains to Cergy and Poissy. TECHNICAL CHARACTERISTICS Length : 108KM Rolling stock: MI 2N MI 09 ( I'm sorry, I couldn't find another more complete image of the cabin ) MI 2N (bitensión 1500 V CC / 25 KV CA) MI 09 (bitensión 1500 V CC / 25 KV CA) DRIVING MODES various driving systems available; Manual driving is used on the entire line except in the downtown area, between the Nanterre-Préfecture and Val de fontenay / fontenay sous bois stations, where automatic driving is used The driving systems used are the following: N : Neutral CM : Manual driving CMC : Controlled manual driving PA : Autopilot VI : preset speed Well this is all. I hope you like the suggestion and that it receives a lot of support. See you on the roads!! Goodbye !!! (( Sorry if you can't see the images ))
