Line 14 of the Paris Metro crosses the center of Paris and currently runs between Saint Lazare and Bibliotheque François Mitterrand. It was the first automated line of the Paris Metro. Before being put into commercial service, it was known by its project name, Meteor, an acronym of Métro Est-Ouest Rapide.

The Meteor project had the following objectives:

• To reduce the burden on RER line A, which was overloaded on the section crossing Paris
• To connect East Paris with West Paris without using an existing RER line.
• To improve the service road on the left bank of the Seine, especially in the 13th arrondissement.

The French government started the project in 1989. The tunnels were dug between 1993 and 1995. It was opened to the public in 1998 and had its first automatic run in October 1998.

Before the current line 14, there was another line 14 that existed until 1976. It corresponded to the Southern section of the current line 13 (connecting Invalides with Porte de Vanves.)

Work is underway to extend the line south to Olympiades, a region that is currently not served very well.

The OpenVMS Operating System runs Line 14.

Line 14 was designed in a unique fashion. Its floor tiling is not bitumenized, and the landing doors of the stations prevent passengers from falling onto the track or from commiting suicide.

This line will be extended to a new station in 2006 (Olympiades).
