Building and Installing GSM-R Network

The Global System for Mobile Communications-Railway (GSM-R) project ensures digital, secure and dependable communications between train drivers and signallers. Delivering significant benefits across the industry and helping to reduce delays, the GSM-R System increases safety, improves performance and provides better passenger experiences throughout Britain's rail network.
FLI supplied over 2500 towers and monopoles for the GSM-R project. There were many variations in height and design to suit locations and access restrictions, so FLI designed modular flexible ranges. This enabled us to deliver a tower at short notice and create bespoke solutions from standard items. We applied the same principles to our rapid deployment foundations, which were screw piles and steel grillages. These could be installed in a couple of shifts which is so much quicker and less disruptive than pouring concrete.

Delivering total radio coverage across the GSM-R radio network, even in tunnels and cuttings requires a comprehensive network of towers, monopoles and smaller repeater sites, both supplied by FLI Structures. This advanced telecoms infrastructure now underpins a modern, digitally-enabled railway network.
