RB Rail AS, on behalf of the ministries responsible for the Rail Baltica project in the three Baltic states, has submitted a funding application under the CEF-Digital programme “5G Large-Scale Pilots – 5G Coverage Along Transport Corridors.” The application, submitted on 13 February 2025, seeks financial support for the development of railway radio communication infrastructure aligned with the Future Railway Mobile Communication System (FRMCS), while also enabling 5G connectivity within the European Transport Network (TEN-T).
The funding request focuses on the initial phase of passive infrastructure deployment along the Rail Baltica mainline in Estonia, Latvia, and Lithuania. The planned work includes radio coverage modelling, design, and the construction of 99 radio towers, providing connectivity for 297 km—equivalent to approximately 30% of the Rail Baltica corridor. These developments aim to support FRMCS implementation, a modern railway communication standard designed to enhance operational efficiency and safety, while also facilitating 5G network coverage. Additionally, the project includes the installation of dark fibre in Estonia and the creation of local connection points.
“Our latest funding application is an important step in advancing Rail Baltica’s digital infrastructure. By adopting FRMCS-compliant technology, we are improving operational capabilities and contributing to stronger integration within the European Transport Network. It must be considered that Rail Baltica crosses areas where current connectivity is unavailable. The deployed infrastructure will allow the installation and operation of a 5G network, securing connectivity for railway passengers, businesses, and surrounding areas,” said Marius Narmontas, COO and Vice-Chairperson of the Management Board at RB Rail AS.
The CEF-Digital programme, launched in late 2024, prioritises projects of European significance that are ready for implementation. The initiative supports the deployment of FRMCS and the expansion of 5G coverage along TEN-T corridors. The evaluation of funding applications is expected to be completed by summer 2025.
