Siemens Mobility has reached a major technological milestone in Finland by carrying out the first Nordic Automated Train Operation on a European Train Control System-equipped mainline. The demonstration took place on the 19-kilometer-long route connecting Juurikorpi and Hamina, marking the first Nordic Automated Train Operation of its kind in the region. During the test, Siemens Mobility successfully integrated Automatic Train Operation with the European Train Control System Level 2, demonstrating how digital rail technologies can operate effectively on a real-world mainline. The trials used a modernized train owned by Pääkaupunkiseudun Junakalusto Oy (JKOY) and operated by VR-Yhtymä Oyj (VR). Through these semi-automatic (GoA2) test runs, the company highlighted precise automated stopping, smooth acceleration, and controlled braking, showcasing the reliability and repeatability of the system. The first Nordic Automated Train Operation also demonstrated how advanced automation can enhance rail capacity, efficiency, and punctuality by maximizing the use of existing infrastructure.
During the test runs, the train executed an automated stop from 100 km/h with a precision ranging between 30 and 80 centimeters. The system also demonstrated consistent acceleration and braking while operating under ATO supervision, confirming stable performance in real-world operating conditions. This achievement further reinforces the capabilities of the integrated European Train Control System Level 2 and onboard automation technologies. ETCS serves as a standardized signaling and control system that improves rail safety by continuously monitoring train speed and movement authority. By replacing fragmented national signaling systems with a unified European standard, ETCS strengthens safety and interoperability across rail networks. When combined with ATO, the system automates key operational functions such as acceleration, coasting, braking, and stopping, improving traffic flow, punctuality, and energy efficiency.
The first Nordic Automated Train Operation demonstration also aligns with Finland’s broader efforts to modernize its rail infrastructure through the Digirail initiative. In 2024, Siemens Mobility secured two contracts linked to this national program aimed at upgrading railway systems. As part of the project, Siemens is equipping two trains with onboard unit technology for testing purposes, allowing seamless communication between trains and rail infrastructure. The resulting advanced train control system is expected to increase network capacity, improve safety, and minimize operational disruptions.
Alongside these developments, Siemens Mobility is modernizing the first commercial section (EKA) of the Tampere–Pori/Rauma line using Signaling X. This cloud-ready, virtualized platform utilizes commercial off-the-shelf (COTS) hardware, enabling simplified infrastructure and more efficient rail operations. The first segment of the project is planned to be operational by 2029, representing an important step toward safer and more sustainable rail transportation.
Led by Finland’s Ministry of Transport, the Digirail program will introduce ETCS nationwide, replacing aging signaling systems. Within this transformation, Siemens Mobility plays a key role in supporting Finland’s transition to safer, more efficient, and digitally advanced railway operations.
