The Next Generation of Railway Communications
The Railway Is Moving from GSM-R to FRMCS
FRMCS will transform how railway communications, digital infrastructure and operational systems are designed, integrated and managed.
As the next-generation, 5G-based successor to GSM-R, the Future Railway Mobile Communication System will support mission-critical railway communications while providing the connectivity foundation for increasingly digital and automated rail operations.
FRMCS & The Connected Railway 2027 brings together railway infrastructure managers, operators, telecoms and digital infrastructure specialists, OEMs, systems integrators, technology providers and programme leaders to address the practical transition from GSM-R to FRMCS.
With Great Britain examining its proof-of-concept (PoC) requirements, migration architecture and deployment strategy, and European testing and validation programmes progressing, the conference connects emerging technical experience with the decisions required for national implementation.
The discussion moves beyond the standard itself to address 5G network architecture, spectrum, radio coverage, trackside infrastructure, mission-critical services, integration, interoperability, procurement, cybersecurity and operational resilience — and the digital railway capabilities that FRMCS will enable.

From GSM-R Migration to the Connected Railway
Three interconnected challenges define the transition to next-generation railway communications.
From Proof of Concept to Deployment
UK readiness, proof-of-concept objectives, GSM-R coexistence, migration sequencing, technical validation, procurement and operational implementation.
5G & Mission-Critical Infrastructure
Radio networks, spectrum, digital infrastructure, mission-critical voice and data, secure connectivity, coverage and resilience.
Connected Systems & Future Operations
ETCS, onboard and trackside systems, interoperable digital platforms, operational intelligence and increasingly automated railway operations.
Conference Focus
The Critical Decisions Shaping FRMCS Deployment
Bringing together the organisations responsible for planning, specifying, financing, engineering, integrating, deploying and operating the UK's and Europe's next generation of railway communications and connected digital infrastructure.
UK FRMCS Readiness, Proof of Concept & Migration
GSM-R lifecycle, UK proof-of-concept requirements, technical and operational validation, national architecture, governance, procurement and the transition towards deployment.
European FRMCS Trials, Testing & Deployment Lessons
MORANE2, national test environments, field validation, interoperability, cross-border requirements and emerging approaches to migration.
FRMCS Radio Networks, Spectrum & Architecture
5G radio access and core networks, Railway Mobile Radio spectrum, mission-critical services, public and private networks, hybrid architectures and resilience.
Trackside Networks, Fibre, Coverage & Integration
Radio coverage planning, site and asset readiness, masts, antenna systems, fibre and backhaul, infrastructure adaptation, network integration and service assurance.
Onboard Connectivity, ETCS & Digital Railway Systems
Cab radios, onboard gateways, train-to-ground communications, ETCS/ERTMS integration, digital data exchange, interoperable applications and connected operations.
Procurement, Cybersecurity & Operational Assurance

Who Should Attend
For the People Designing, Building and Operating the Next Generation of Railway Communications
FRMCS & The Connected Railway 2027 is designed for senior decision-makers, programme owners, technical authorities, engineers and technology specialists working across rail telecommunications, digital infrastructure, operational systems and railway modernisation.
If your organisation is involved in the migration from GSM-R to FRMCS, the delivery of next-generation rail communications infrastructure, or the digital services and operational systems that depend on it, this forum is designed for you.
