Getting more trains on the track
At SNCF you’ll help spread the adoption the European Rail Traffic Management System (ERTMS). This new pan-European signalling system improves reliability and on-time performance by cutting headway—the interval between two trains travelling on the same track—in half. We’re now installing the system on lines between Marseille and Ventimiglia, with Paris-Lyon scheduled for 2025. ERTMS will allow us to run up to 16 trains per hour between the two cities.
Lower energy consumption, fewer breakdowns
We’re using new smart systems for precision acceleration and braking. The “green driving” systems now in development will cut trains’ energy consumption by 10-15%. Wider use of predictive maintenance also promises to dramatically reduce the number of breakdowns and improve service quality.
Making mobility more accessible
Developer, project lead and data analyst are just a few of the jobs on offer. Designing innovations to make mobility more accessible for all is the key focus of SNCF Connect & Tech, a private-sector subsidiary of French e-commerce leader SNCF Voyageurs. Its 1,300 employees implement customer-facing digital solutions in the mobility sector, chiefly via the SNCF Connect app, which logs 16.5 million customers and 1.55 billion visits in 2024.
Tesmo, a new brand launched by SNCF Connect & Tech
Starting in 2025, Tesmo, which stands for Technologies Serving Mobility, is designed to cater to other players in the mobility sector, such as private companies and local authorities. It vows to put our expertise and know-how to good use by offering our services to new customers in France and Europe, and thus serve sustainable mobility.
Ticketing—and much more
We operate France’s #1 e-commerce site and sell 550,000 train tickets a day through our SNCF Connect app. But we’re also developing tools that go well beyond online ticket sales. Examples include:
- live information for SNCF employees and passengers
- onboard digital tools for a better, safer travel experience
- solutions tailored to the very specific needs of Transport Organizing Authorities
