Paris Métro Line 1
The Parisian metropolitan network has its origins in several decades of debate, more or less bizarre projects and tug of war between the State (which was favourable to the interconnection of large rail networks with large undergrounds) and the City Hall of Paris (which wanted a small-scale network, serving only the inner city with very close stations, effectively prohibiting access to the equipment of the large railway companies). The deterioration of traffic conditions in Paris, the example of foreign capitals and the approach of the 1900 Universal Exhibition convinced the authorities to start construction of the metro. The solution proposed by the Mayor of Paris was finally adopted; the State conceded the design and construction of the work to the City of Paris. After the adoption by the municipal council on 20 April 1896 of the network project of Fulgence Bienvenüe and Edmond Huet, the "metropolitan railway" was declared a public utility by a law that became effective 30 March 1898. In November 1898, the City of Paris decided to undertake preliminary work of the metro network with the construction of the first line of the Parisian subway system. Work lasted twenty months under the leadership of engineers Fulgence Bienvenüe and was financed by the municipality of Paris. The line was divided into eight parts distributed among several companies. On 19 July 1900, the line was opened between Porte Maillot and Porte de Vincennes to connect the various sites of the World Fair. Only eight stations were finalised and opened with the inauguration; ten more were gradually opened between 6 August and 1 September 1900. The line followed the east–west monument axis in Paris. These eighteen stations were entirely built under the control of engineer Fulgence Bienvenüe, the majority of them 75 metres long and 4.10 metres wide. In March 1934, the first extension into the suburbs brought service to Château of Vincennes towards the east. Line 1 has had five different types of rolling stock throughout the years: After successfully opening Line 14 as a fully automated line, the RATP began to explore the possibility of automating existing lines on the system. The agency first focused on Line 1, since it is the busiest of all of the Paris subway lines, and also the line most frequented by tourists. Automation not only allowed Paris to remain as a model for technological innovations in the railway industry but also increases the number of lines in normal service when RATP workers are striking (MP 05 rolling stock). This was shown when the transport union engaged in industrial action in September 2019 without affecting service on Line 1.
Work began in 2007 and was largely carried out without interrupting passenger traffic. Preliminary work involved electrical and signaling upgrades throughout the entire line. Work also commenced on converting the original Porte Maillot station (also known as "Espace Maillot") into a light maintenance facility for the MP 05 rolling stock. In 2009, work commenced on installing platform screen doors; with Bérault and Porte Maillot being the first stations to be equipped. Due to its curved platform, Bastille (in 2011) was among the last stations to be equipped. During this time, individual stations were intermittently closed to allow platforms to be leveled with the height of the train floors (from :fr:Ligne 1 du métro de Paris). Although most of the stations remain the same as they were prior to automation (with the exception of the platform screen doors), many stations like St. Paul, received brand new signage. Franklin D. Roosevelt received a complete overhaul from its post World War II facade to a more contemporary & modern look. On 3 November 2011, the first eight trains of the new MP 05 rolling stock were put into service on Line 1. These trains ran alongside the MP 89 CC rolling stock until enough automated stock was available for passenger service. This cascading was achieved thanks to the SAET () system, which is the first version of Siemens Transportation Systems' Trainguard MT CBTC. The arrival of the new stock allowed the RATP to accelerate transfer of the MP 89 from Line 1 to Line 4 at a rate of about 2 to 3 trains per month between November 2011 and November 2012. That rate increased to 4 trains per month during November and December 2012. Major milestones were reached in May and July 2012 as full automation reached sufficient levels by which the MP 89 were no longer needed during late evenings and weekends respectively. For the "Nuit Blanche" during October 2012, Line 1 also operated in full automation. The final milestone was reached on 15 December 2012, as full automation of Line 1 approached 100%, allowing the remaining MP 89 trains to be pulled from regular service on 21 December 2012. Due to insufficient storage space on Line 4, the remaining 6 to 7 MP 89 trains remained stored on the Line 1 tracks near Fontenay until a new garage in the Montrouge area opened. That opening was tentatively set for February/March 2013 and will coincide with the opening of the new Mairie de Montrouge station opening on Line 4. A western extension of Line 1 from La Défense station to the center of Nanterre is being considered. Another proposal being investigated would have a new station constructed at Fontenay – Rigollots, just before the line climbs to the surface to enter Fontenay shops, and then continue eastward to Val de Fontenay to connect with RER lines A and E. This line has 25 stations. Line 1 passes near several places of interest:
History
The line was the network's first to open, with its inaugural section entering service in 1900.
