In the rail sector, optical fibre has become a reliable, fast and less expensive means of telecommunications than the traditional copper cable transmission.
Terralpha, ultra high-speed broadband at the heart of the regions
In May 2021, SNCF Réseau is creating a new subsidiary, Terralpha, with the ambition of making the most of available optical infrastructures that are not operated for railway activities. The mission of the Terralpha subsidiary is to make the most of the surplus fibre available through strategic partnerships, helping to reduce the digital divide.
Terralpha offers an ultra-high-speed data transport service to its customers and partners, including fixed and mobile network operators, hosting and data centre operators, major manufacturers, public initiative networks and all other public players.

The emergence of Edge Computing
The digital trust service from Terralpha extends to the construction of Digital tiles.
These landscaped areas are ideal for microDataCenter in railway rights-of-way by telecoms players,
which will benefit from carrier-grade energy, data, surveillance and access services.
Terralpha, a solid and resilient operator, subsidiary of SNCF Réseau
To meet the growing need for mobility and develop the rail mode to serve the ecological transition, SNCF Réseau is developing the service offer for freight and the passenger market on the 28,000 kilometres of line for which it is responsible for maintenance, modernisation and safety.
As network manager, it markets and guarantees neutral and fair access to the infrastructure. As a partner to public authorities, regional authorities and railway companies, SNCF Réseau's top priority is customer satisfaction. A limited company in the SNCF Group, the company has more than 50,000 employees and a turnover of almost 6.6 billion euros in 2021.
Created in 2021 by SNCF Réseau, Terralpha can count on its sovereign parent company to respond to the major changes shaping our society, by speeding up its transformation to help boost the role of ultra high-speed data transport in economic and industrial efficiency, regional development and environmental protection.
