The Lausanne Métro Line M1, is a light rail line which links Lausanne-Flon, in the centre of Lausanne, to Renens, to the west of the agglomeration. The line serves an important purpose as it goes through the Lausanne campus, making it a crucial transport method for students accessing their university. In 2013, its ridership was 13.2 million, making it the lesser-used line of the Lausanne Métro at this time.

The Lausanne Métro system is a two-line urban rail transport system in Lausanne, Vaud, Switzerland. Around a quarter of the system has been used for urban rail transport since 1877, when the route between the city centre and Ouchy opened as Switzerland's first public funicular railway. The network is owned by two distinct companies and operated by a third.
