Each station is materialized around an imaginary theme linked to the underground, which comes to life and is electrified when the metro train arrives. A true station icon, the animated decor helps identify the place while belonging to the overall theme: the journey in the underground.

Here are the themes chosen for each station:

• Blécherette: wind erosion / wind dynamics
• Plaines-du-Loup: Glacio-lacustrine layer / Bioluminescence
• Caserne: Quartz cavern / Acoustic resonance
• Beaulieu: Upper crust / Seismic activity
• Chauderon: Rare metals / Technological components
• Lausanne-Flon: Aquifer / Underground lake
• Lausanne-Gare: Core / Convective flows

For the final round of the competition, the Stratorielle team developed:

A modular urban furniture design made in hardwood, a suspended light system as well as LED bars that intensify at the arrival of each train, a simple but effective signage echoing the one of the M2 metro, a generative system to help placing the different elements according to certain spatial conditions, a choice of cladding and materials for the stations, a prototype of informative interactive screens with the theme “strata” in the form of video animations, a complete model of the station at 1/50 scale as well as an interactive luminous model of the identity decors of each station at a scale of 1/20. It is accompanied by sounds (with a mineral resonance) and voices - of different inhabitants of the district - announcing the names of the stations.
