The
<dfn>Paris Métro line 14 before 1976</dfn>, also called
<dfn>line C</dfn>, was planned as line C of the
Nord-Sud Company (line A being today's
line 12 and line B being today's
line 13). The Nord-Sud company went bankrupt in 1930 and was taken over by the other company operating Paris metro: the CMP (which later became the RATP). The CMP subsequently implemented Line C as line 14. In the 1970s, the line was incorporated into
line 13.
