Railways

Connecting communities, enabling innovation

Railways and underground systems are undergoing a period of transformation towards digitalisation. Transport authorities must address new challenges, enhance the user experience, and ensure the operational excellence of their systems. The objective is to transform stations into intermodal hubs.

Cellnex implements cutting-edge connectivity throughout the entire railway system — from stations to tunnels and along the corridors — using the most suitable technology in each area to meet end-user needs.

In addition, it provides dedicated and fail-safe communication networks, ensuring visitor safety and maintaining consistently secure working conditions.

Connectivity in underground transport systems

We have implemented the critical communications network and we manage the connectivity project on Line 9 of the Barcelona metro, a complex project designed for a large line: more than 47 km of tunnels, 50 stations, 2 train sheds, a workshop area… Find out the technology that supports these connections and allows us to always have connectivity underground.

Working on and around the railway is not easy. Good mutual cooperation and short lines of communication are therefore crucial. The Cellnex and our own specialists complement each other perfectly.

The number of train passengers will increase by 30 percent in the next twenty years. This means that more passengers will require mobile coverage and internet access on trains. This project achieves two things: it creates an important condition for running more trains and ensures that all those people have even better mobile coverage.
