The Digirail project is moving toward the implementation of a new radio-network-based train control system on the first commercial track section in Finland. The test readiness achieved on the Kokemäki–Rauma track section enables the system to be tested in a real-world rail environment and moves the project toward its first field tests and test runs.
The Digirail project has reached a significant milestone on the Tampere–Pori/Rauma section, as testing of the system integration is set to begin on the Kokemäki–Rauma section. This marks an important step in the project’s progress from the laboratory phase toward field testing and subsequent test runs.
The test readiness achieved on the Tampere–Pori/Rauma track section meets the key milestone set for EU funding for the track section. We can now begin to test the performance of the systems under real-world conditions in the field.
Digirail utilises an open and standardised architecture in which different parts of the system can be implemented using solutions from different vendors. For example, the CSS and OC systems come from different vendors, which reduces dependence on a single provider and increases competition in system development. This model enables more cost-effective implementation and allows for more flexible adoption of new innovations and technologies also in the future.
Digirail is gradually modernising Finland’s current train control system. The Tampere–Pori/Rauma track section serves as the project’s first commercial application, where preparations are underway to implement the European Train Control System (ETCS) and related new radio–network-based solutions.
Testing moves from the lab to the track
Site Integration Testing (SIT) ensures, step by step, that the system integration functions as planned also in a live environment. Previously, integration testing between systems was conducted in a laboratory environment at the Rail Training Centre in Kouvola.
On the Kokemäki–Rauma track section, test readiness has been built to include the following facilities, among others:
- balises
- axle calculation points
- shunting signals.
In the next phase, the systems will be tested in the field in conjunction with the Centralized Security System (CSS). If field testing proceeds as planned, test runs using a locomotive under the supervision of an inspector can begin in the autumn of 2026.
“The Digirail project is currently building the rail transport system of the future in Finland.” “The test readiness we have now achieved is an important indication that the new radio-network-based train control system is progressing as planned toward commercial operation,” says Project Manager Aapo Tiilikainen.
Digirail’s first commercial track section
Digirail’s first commercial track section (EKA) will be located on the Tampere-Pori/Rauma line. The track section is approximately 190 kilometers long and serves as a pilot project for a new train control system in Finland.
With this project, Finland is taking a significant step toward the digitalization of its railways, as a radio-network-based ETCS system is being built for commercial use for the first time. In Finland, the system has so far been tested on a test track outside of regular operations, but now the solution is being rolled out for the first time for use in commercial passenger and freight train services.
The Digirail project is making rail transport in Finland safer, smoother and more efficient. The project is reinventing the outdated train control system and introducing a shared European radio-based train control system across the entire rail network. Digirail will enable safe transport, an improved service level and growth of capacity, and it will create a long-term technical foundation for Finnish railway traffic. The Finnish Transport Infrastructure Agency, Fintraffic and the Ministry of Transport and Communications are collaborating in the project with other actors.
