Station

Nanterre-Préfecture is an underground station located close to the prefecture of the department of Hauts-de-Seine, hence the name. The central part of RER A, as well as A1 to Germaine-en-Laye, are operated by RATP. The branches A3 to Cergy and A5 to Poissy are operated by SNCF. The station has the central platform, where trains depart to the center of Paris, and two side platforms, one for A1 and one for A3/A5.

History

In 1965, following the extension of the agglomeration far beyond the city limits of Paris, RATP and SNCF came out with the plan of the transport network development, which, in particular, included the development of RER. In 1969, RATP bought from SNCF the railway connecting Boisy-Saint-Léger and Bastille and built a stretch between Bastille and Nation. On 14 December the new line (RER) started operation.[1] On 21 January 1970, RATP bought a railway line between Gare Saint-Lazare and Saint-Germain-en-Laye ("ligne de St-Germain"). On 1 October 1972, the service started between Auber and Saint-Germain-en-Laye. This stretch was not yet connected to the eastern part of RER A. In October 1973 the station of Nanterre-Préfecture was open in the existing tunnel and started operation. On 9 December 1977, the western and the eastern stretches were connected, and thus Nanterre-Préfecture was placed on RER A line. On 29 May 1988, service in the direction of Cergy started.^{[citation needed]}

Passenger traffic

More than 21,000 passengers daily used the station as of 2011. The number of passengers was predicted to increase to 25,000 by 2012, because of the construction around the station with the goal of improving its accessibility.[2]
