Digital Rail Signalling Upgrade Supports Finland’s ERTMS Transition
Sweco will support Finland’s rail modernisation programme with signalling design and commissioning services as the country adopts the EU-standard ERTMS platform.

Rail infrastructure operators across Europe are replacing legacy signalling systems with interoperable digital train control architectures to improve operational consistency, cross-border compatibility, and long-term network resilience. Finland’s latest contracts with Sweco reflect this transition, supporting the phased deployment of the European Rail Traffic Management System (ERTMS) across major sections of the national rail network.
ERTMS Deployment as National Rail Infrastructure Modernisation
The Finnish Transport Infrastructure Agency (Vaylavirasto) has selected Sweco to provide consulting services for Finland’s implementation of ERTMS, the EU’s standardised digital signalling and train control framework.
The contracts cover signalling design services and commissioning inspection services over an eight-year period, with an estimated combined value exceeding EUR 24 million.
Sweco will participate as part of an alliance delivery structure, supporting the replacement of rail safety equipment and traffic control systems as Finland transitions toward a digitally standardised railway infrastructure.
ERTMS implementation across the Finnish rail network is scheduled between 2028 and 2040, positioning the programme among the country’s largest long-term transport infrastructure modernisation initiatives.
Signalling System Engineering and Commissioning Scope
Under the contracts, Sweco will design upgrades for railway signalling safety infrastructure and associated traffic control systems while also conducting expert commissioning inspections.
The contract scope covers approximately 970 kilometres of railway in Western and Southern Finland.
Engineering work is scheduled to begin in the third and fourth quarters of 2026, with project delivery continuing through 2034.
Commissioning inspection services are particularly relevant in signalling migration programmes, where validation of safety-critical infrastructure is required before operational deployment.
Why ERTMS Matters for European Rail Interoperability
ERTMS was developed to replace fragmented national signalling systems across Europe with a unified framework supporting train interoperability, operational safety, and digital traffic management.
The framework combines the European Train Control System (ETCS), which manages train movement authority and speed supervision, with GSM-R or successor communications infrastructure for train-to-control-centre connectivity.
For countries such as Finland, adoption improves compatibility with wider European freight and passenger rail operations while reducing long-term dependence on bespoke signalling infrastructure.
The shift also supports broader rail digitalisation strategies, where traffic management, predictive maintenance, and cross-border operational coordination increasingly rely on standardised digital infrastructure.
Long-Term Rail Network Resilience and Capacity Planning
Replacing legacy signalling systems is not solely a compliance exercise.
Digital train control infrastructure can improve operational precision, reduce signalling system obsolescence risks, and create a foundation for future automation and network optimisation.
In Finland’s case, phased implementation over more than a decade reflects the technical complexity of replacing operational safety systems without disrupting national rail services.
Sweco’s prior involvement in earlier programme phases suggests continuity in engineering knowledge, which can reduce design transition risks in long-duration infrastructure programmes.
