08 Nov 2025
Ireland - 4 Novemder 2025, Iarnæ Éireann An important milestone in the modernisation of Ireland's railway signalling infrastructure has been reached when Irish Rail awarded Siemens Mobility Ltd. a €263.25 million contract for the long-term supply and support of a Computer-Based Interlocking (CBI) system. The agreement, which was formally signed on November 4, 2025, demonstrates Irish Rail's dedication to enhancing network security, operational dependability, and signalling effectiveness over the following 25 years.Summary of the ContractA Computer-Based Interlocking Cabinet's supply, installation, and ongoing maintenance are covered by the award, which is published under Document No. 732627-2025 and reference 7863. To guarantee safe and effective train movements, the system will handle route-setting commands and manage trackside machinery. Lineside Electronic Units (LEU) and Object Controllers (OC), which are essential parts that monitor and control railway signals and points throughout the network, are also part of the project.Iarn Éireann's €263 million contract is a strategic infrastructure investment with the goal of moving to digital signalling technologies in accordance with European rail safety and interoperability standards. Ireland's railway modernisation programme will be technologically supported by the CBI system, which will enhance service reliability and set up the network for future capacity expansion.Organisations ConcernedThe procuring authority, Iarnród Éireann – Irish Rail, headquartered at Connolly Station, Dublin, is the national railway operator responsible for passenger and freight services across Ireland. The project was managed under the supervision of James Rattigan, representing the organisation’s signalling and telecommunications division. The successful bidder, Siemens Mobility Ltd, based in Wiltshire, United Kingdom, is a global leader in rail automation and digital transport systems. Siemens Mobility has a long history of collaboration with European rail networks, providing advanced interlocking, train control, and digital maintenance solutions designed for safety, scalability, and sustainability.Strategic ImportanceThe long-term CBI system project represents a critical leap toward digital railway transformation in Ireland. Traditional mechanical and relay-based interlocking systems will be gradually replaced with modern computer-controlled infrastructure, enabling faster route setting, enhanced fault diagnostics, and improved operational coordination. Beyond improved safety and efficiency, the investment supports the Irish government’s broader National Development Plan and Climate Action Strategy, which emphasize greener, technology-driven transport infrastructure. By implementing a scalable interlocking solution, Irish Rail ensures its network is future-ready for increased passenger and freight demands and potential integration with European Rail Traffic Management System (ERTMS) standards.ConclusionAn important milestone in Ireland's railway modernisation process has been reached with the awarding of this €263 million, 25-year contract to Siemens Mobility Ltd. The Computer-Based Interlocking system will revolutionise operational safety and signalling dependability throughout the country as it is implemented. Ireland's long-term goal of having a more intelligent and sustainable rail system that is in line with international best practices in digital control and rail automation is reflected in this partnership.
