Terralpha, ultra high-speed broadband at the heart of the regions
Our history
In the rail sector, optical fibre has become a reliable, fast and less expensive means of telecommunications than the traditional copper cable transmission.
To date, SNCF Réseau has deployed a network of almost 20,000 km of fibre optic cables throughout France as part of its modernisation programme.
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.

Our missions
Terralpha provides all professionals with ultra-broadband solutions tailored to their business challenges: performance, security, sovereignty and enhanced customer experience.
Thanks to the extent of our network and our sovereign infrastructure, fully owned along the railway lines, we are able to offer optimal territorial continuity throughout France. We provide digital players and operators with an infrastructure that enables them to accelerate the development of their solutions.
Because the optical fibres are laid along the tracks, we can transport data at very high speed, offering one of the best latencies on the market.

The emergence of Edge Computing
Terralpha's digital trust service has been extended to include the construction of Digital Slabs.
These spaces can be used by telecoms operators to set up micro-DataCenters on railway rights-of-way, offering carrier-grade energy, data transport, 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.
