Paris Métro Line 14 (1937–1976)

Paris Métro Line 14 (planned as Line C; French: Ligne 14 du métro de Paris) was a line of the Paris Métro that existed from 1937 to 1976.

History
Designed as Line C of the Nord-Sud Company—Line A being today's Line 12 and Line B being today's Line 13—before it went bankrupt in 1930, the project was taken over by the other company operating the Paris Métro: the Compagnie du chemin de fer métropolitain de Paris (CMP), which would become the Régie autonome des transports parisiens (RATP) in 1949.

The CMP subsequently started building Line 14 in 1933. In 1976, the line was incorporated into Line 13 with the opening of the extension between Invalides and Champs-Élysées–Clemenceau under the Seine, as Nord-Sud's original plan included a merger of Line B and Line C. The number 14 was reused for a new line that entered service in 1998 between Madeleine and Bibliothèque François Mitterrand.
