Mipro Oy selected as supplier of EULYNX-based Object Controller System for Digirail project in Finland 

Mipro Oy will supply the Object Controller System (OCS) for the first commercial ERTMS/ETCS track section (EKA) of the Digirail project, covering the Lielahti–Rauma/Pori line, as part of the modernisation of Finland’s railways. The Digirail project will upgrade Finland’s train traffic control system to improve safety. In this project, Finland is acting as a European pioneer, utilising the highest safety-level technology and solutions that comply with the EULYNX standard. 

Mipro has been selected as the supplier of object controllers for the first commercial rail section (EKA) of the Digirail project. The project covers the Digirail EKA section from Lielahti to Rauma/Pori. Work has already begun with the specification and planning phase. 

The procurement process for the project started in the winter of 2024 and progressed through a negotiation procedure and tender submissions, leading to a contract. The contract was signed in October 2024, and the project started immediately afterwards. The project is scheduled to continue until spring 2027. 

The Digirail project will modernise Finland’s train traffic control system, making it safer, more efficient, and more environmentally friendly. By adhering to EU standards and implementing the European Train Control System (ETCS), the Digirail project will integrate Finland’s railways more closely with the European network. The project employs the latest radio network technology and cybersecurity solutions, and also promotes Finnish innovation capabilities internationally. 

“With the Digirail project, we are entering a new territory, as for the first time in Finnish history, the interlocking system has been divided into two parts. Previously, Digirail signed a procurement contract with Siemens for the centralised safety system, and now we have signed an agreement with the domestic company Mipro for the supply of object controllers. This is highly significant on a European level, as having different equipment suppliers will allow us to be the first in Europe to test the functionality of the EULYNX interface and to gain valuable insights from the EKA railway section for the implementation phase of the Digirail project. We are very much looking forward to this collaboration with Mipro,” says Project Manager Juha Lehtola from the Finnish Transport Infrastructure Agency. 

“For Mipro, the object device controller contract is extremely important, and we are pleased to be part of the first phase of the Digirail project on the EKA track section. This is a significant milestone for Mipro, as we are the first in Europe to develop an object device controller based on the EULYNX interface, an open interface that paves the way for European train control through the ETCS architecture,” says Mipro’s Business Unit Director Jari Pylvänen. 

The Object Controller System operates the object devices of the railway safety system, such as switches and track signals, and detects trains using an axle counting system. OCS serves as a link between Centralised Safety System (CSS) and the trackside equipment. The system uses technology with the highest safety level (SIL4) and incorporates new solutions in line with the European EULYNX standard. 

“Mipro is proud to be at the forefront of providing world-class solutions for the EKA line, helping Digirail to achieve its goals in a rapidly evolving technological environment. Mipro’s next generation object controllers comply with the EULYNX BL4R2 standard and include a cybersecurity solution in accordance with IEC62443. This allows us to manage the risks of external interference in a changing global situation. In addition, the system offers comprehensive remote diagnostics and management capabilities that increase system availability and simplify maintenance,” says Mipro’s Chief Technology Officer, Kari Haapala.

Mipro’s systems are used in railway and metro safety management, industrial process safety, and the control of water and energy supply processes. Headquartered in Mikkeli, this growing company operates in global markets. In Finland, its clients include the Finnish Transport Infrastructure Agency, Fintraffic, Helsinki Metropolitan Area Transport Ltd., and numerous water and energy utilities. 

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.
