Stadler Wins Dublin-Belfast Enterprise Contract: 8 New Trains & Maintenance

Irish Rail and Translink have officially awarded a significant contract to Stadler for the supply of eight new high-generation trains to modernize the crucial Dublin–Belfast Enterprise rail service. This agreement, encompassing a 15-year maintenance commitment with an extension option, is set to usher in a new era of passenger experience and operational efficiency, despite an initial procurement challenge.

The landmark contract, formalized after a procurement process that saw a temporary injunction lifted by the Supreme Court, will see Stadler deliver a fleet of eight new trains based on its proven Flirt platform. This modernization initiative is paramount for enhancing passenger connectivity between Dublin and Belfast, directly supporting strategic objectives for reduced emissions and increased accessibility across the island of Ireland.

Strategic Importance of the Enterprise Service Upgrade

The decision by Iarnród Éireann and Translink to procure new rolling stock for the Dublin–Belfast Enterprise service marks a pivotal moment in cross-border rail infrastructure development. The new trains are designed to be dual-mode, operating on Irish Rail’s 1,500 V DC electrified network and in diesel mode, crucially incorporating integrated batteries for zero-emission operation over short distances, such as within the new Belfast Grand Central station precinct and to the York Road depot. This forward-thinking design future-proofs the service against evolving electrification strategies and environmental mandates, underscoring the operators’ commitment to sustainable transport solutions.

Advanced Technical and Accessibility Features

Stadler’s Flirt platform trains are engineered for optimal passenger comfort and operational flexibility. Each train will feature articulated carriage pairs, eight motor bogies for enhanced performance, and wide central doors equipped with movable steps to facilitate level boarding for improved accessibility. Low-floor areas throughout all carriages and dedicated pushchair spaces, strategically located away from toilets, address specific accessibility needs. The interior design also prioritizes passenger experience with a mix of bay-type and unidirectional seating configurations, six bicycle spaces, and eight toilets, two of which meet PRM-TSI standards. The innovative “power car” design, housing diesel engines at the conductor end and eliminating underfloor units, allows for straightforward conversion to full 25 kV AC electric traction when the Northern Ireland network is upgraded.

Operational Readiness and Future-Proofing

The contract stipulates a phased introduction of the new trains, with deliveries commencing in 2028 for an intensive testing period. Full operational service is slated to begin in 2030, coinciding with the planned withdrawal of the current Class 201 locomotives and De Dietrich carriages. The driver’s cab maintains the established Flirt ergonomics, with a central driver’s seat and space for a second crew member. Advanced systems including ETCS (European Train Control System), selective door opening, and 22 external CCTV cameras ensure enhanced safety and operational control. The comprehensive 15-year maintenance agreement, with an option to extend for an additional 15 years, guarantees long-term support and reliability for this critical intercity link.
