Porte Maillot is a station on Paris Métro Line 1 and on the RER C. The station replaces another station of the same name, the original terminus of Line 1, which was demolished and moved in 1936.
The name derives from a former gate to the Bois de Boulogne, whose name derives perhaps from maille, or croquet.
Paris Métro Line 1 is one of the sixteen lines composing the Paris Métro (in Paris, France). It connects the La Défense – Grande Arche and Château de Vincennes stations. With a 16.5 km length, it constitutes an "East-West" route transportation important for the City of Paris. Excluding RER (French: Réseau Express Régional) lines, it is the most utilised subway line on the network with 213 million travellers in 2008 and 725,000 people per day on average.
Line 1, as indicated by its name, was the first one to open, its first section opened in 1900.
Between 2008 and 2011, a project was undertaken to make Line 1 fully automated, as the Line 14. Automation process included new rolling stock, MP 05, and laying of platform edge doors in all stations. The construction process was completed during summer 2011 and the first eight MP 05 trains (#s 501 through 508) went into passenger service on November 3, 2011 [1][2]. Transfer of the existing MP 89 stock from Line 1 to Line 4 began in May, 2011 with train #01. Since then, a total of ten trains have been moved to Line 4 (as of December 21, 2011) [3].
