Alstom Postpones Irish Train Launch Amid Essential Battery Modifications
Alstom has announced a significant delay in the launch of their X’trapolis trains designated for Irish Rail. Initially slated for late 2025, the schedule has been pushed to the first quarter of 2027. This change is primarily due to essential modifications being made to the Li-Ion traction batteries used in these trains.
Issues with Battery Reliability
Mary Considine, the CEO of Irish Rail, explained that the Li-Ion traction batteries for the X’trapolis trains are similar to those found in Melbourne’s Flexity 2 trams. However, the Flexity trams have experienced reliability problems during their testing phase. To address these concerns, Alstom and the French battery manufacturer OP Mobility have opted to redesign the batteries included in the X’trapolis trains.
Testing and Development Timeline
Despite the ongoing battery challenges, Considine assured that there were no battery-related issues detected during the year-long testing period of the X’trapolis trains themselves. The redesign process will necessitate a recertification of the batteries before they can be deployed.
Contractual Obligations
Under the terms of a 2021 contract, Alstom is committed to supplying a total of 37 five-car trains to Irish Rail. This includes 19 units that will be powered by a combination of catenary and battery systems, boasting an operational range exceeding 80 kilometers.
Implications for Irish Rail
- Launch delayed to Q1 2027
- Battery redesign due to previous reliability issues
- Alstom to provide 37 five-car trains
- 19 units with catenary and battery power
The delay in the launch of the X’trapolis trains illustrates the complexities involved in modern train manufacturing and the critical importance of safety and reliability in public transport.
