Driven by a highly skilled team of specialists, FS Engineering oversees the entire lifecycle of telecommunications infrastructure development. The company holds primary responsibility for the design, validation, and testing of railway telecom networks, which form the vital technological foundation supporting all rail operations. This extensive experience, built up across both conventional mainlines and high-speed networks for domestic and international clients, ensures exceptional levels of system performance, resilience, and operational efficiency.
These systems serve as the digital backbone of the railway network, guaranteeing safe, continuous, and efficient transport services. This is achieved through integrated architectures that combine robust fibre-optic networks, SDH, DWDM, and IP/MPLS transmission systems with the GSM-R mobile network and pioneering solutions like the Future Railway Mobile Communication System (FRMCS).
FS Engineering is actively committed to delivering the modernisation of the Core Network for the IP-based GSM-R transition, alongside developing innovative applications within the FRMCS framework for the Rail Baltica programme. Furthermore, the company is spearheading the renewal of public GSM coverage systems across tunnels on the national rail network, alongside major technological upgrades on strategic routes including the Rome–Florence Direttissima high-speed line, the Rome–Naples line, and the new Naples–Bari infrastructure. Parallel to these communication upgrades, FS Engineering is deploying supervisory control and data acquisition (SCADA) systems for asset monitoring on bridges and lineside infrastructure, while simultaneously delivering energy schemes focused on sustainable solutions to drive the decarbonisation and energy transition of the rail transport sector.
Cable Networks (Fibre Optic and Copper) Design and implementation support for the wide-area fibre-optic and copper infrastructure networks, serving telecommunications and railway signalling systems. This includes the development of wired LAN network projects for signal boxes, offices, stations and stops. |
Transport Network Design and implementation support for wide-area telecommunications networks utilizing SDH, MPLS-TP, IP, and IP/MPLS technologies. These networks support critical telecommunications systems (GSM-R, supervisory control platforms, operational telephony, Passenger Information Systems (PIS), and Station Security architectures) and railway signalling systems (ACCM, SCCM, ERTMS, etc.). |
Data Network Upgrades Design and implementation support for upgrading core transport networks using OTN-DWDM and IP/MPLS technologies. This encompasses the definition of phased evolution plans to expand bandwidth capacity, integrate heterogeneous legacy systems, and enable advanced digital services (including FRMCS, predictive maintenance, Smart Stations, and infrastructure monitoring). It also covers the modernisation of existing IP networks and network synchronisation infrastructure required to support legacy SDH transport assets. |
GSM-R (Global System for Mobile Communications – Railway) Design of GSM-R networks to provide secure, high-priority, and interoperable operational voice and data communications between ground staff and train crews. These networks support traffic management and ERTMS/ETCS systems across conventional mainlines and high-speed routes. This scope includes conducting comprehensive radio coverage studies using specialised planning tools, verifying Electromagnetic Impact Analysis (EIA) outcomes, and delivering the overall radio system dimensioning. |
Technological Upgrade of the Radio Network (FRMCS) Design of technological upgrades migrating the mobile network toward the Future Railway Mobile Communication System (FRMCS) based on 5G railway architectures. This facilitates the deployment of mission-critical broadband communications, IoT field applications, and advanced automation systems tailored for future smart railway infrastructure. |
