In order to respond to the increase in passengers transiting through the Lausanne train station and to serve the developing districts to the north of the city, a third metro line will complete the actual underground network.

In the present project, GEOEG provided expertise on quantifying the impacts of geothermal activation of the Lausanne m3 tunnel.

The study involved preliminary analysis of the implications of incorporating heat exchangers and analysis of structural aspects related to geothermal activation.
