For more than 20 years, we have been the trusted partner of municipalities
Our rigorous approach is based on trust and transparency, our vast technical expertise and a detailed understanding of the needs of every region where we operate.
No matter the municipality's size and regardless of their ambitions, we offer solutions with a single goal: to achieve the municipality's transport ambitions to serve their region.
We combine expertise and ambition, in the service of mobility
Active across all modes of transport, from rail to on-demand transport, from maritime or river ferries to bikes, from urban cable cars to buses, we have expertise in all forms of public transport. We can rely every day on the skills of our 9,000 employees across more than 50 subsidiairies.
We are committed to safety. We believe in practical innovation. We take public transport service to heart. We value dialogue and transparency.
We support all regions with the same standards and passion
We support all regions with the same passion, regardless of their project. In Lyon, we operate and maintain metro lines - including automated lines - trams, funiculars and the Rhonexpress. In Paris, we are preparing for the launch of Line 15 South of the Grand Paris Express: 16 stations and 33 km of fully automated metro service. We support all municipalities, regardless of their ambitions, such as the energy transition of the La Roche-sur-Yon network and the roll-out of BRT in Creil, Aix-les-Bains and Vienne. Every project is unique and every solution is tailor-made.
We have worked alongside municipalities for more than 20 years to support their ambitions while remaining true to our identity: operational excellence, dialogue, a focus on people and safety, practical innovation and attentive management.
