Paris Metro Line 4 is the second busiest metro line serving Paris, France. It crosses the city from the Porte de Clignancourt in the north to the Porte d'Orléans in the south. It is also the line where the temperature is the warmest as it was built at a deep level and it is operated with rubber-tyred trains. The main reasons that Line 4 is one of the busiest and most crowded Metro lines in the city is that it includes stops at three major intercity train stations (Gare Montparnasse, Gare du Nord, and Gare de l'Est) as well as two stations with multiple RER connections (Les Halles and Saint-Michel).
[edit] Chronology
- April 21, 1908 : A first section of the line was inaugurated to the north of the Seine between Porte de Clignancourt and Châtelet.
- October 30, 1909 : A second section of the line was inaugurated south of the Seine between Porte d'Orléans and Raspail.
- January 9, 1910 : Both sections were linked by a new tunnel between Châtelet and Raspail. Line 4 was the first line crossing the Seine river underground.
- 1967 : The rails were converted in order to cater for rubber-tired trains.
- October 3rd, 1977 : The station Les Halles was rebuilt to interchange with the new RER network.
[edit] Future
An extension to the south with one more station (Mairie de Montrouge) is planned for 2011.
Later on, the line may be extended further south with two more stations: Verdun Sud at the frontier between Montrouge and Bagneux (in Montrouge) and Bagneux in Bagneux.
The line is expected to be converted to an automated system (like Line 14), after conversion of Line 1 is completed.
