Renfe and SJ advance rail technology and infrastructure projects

Spain’s state railway operator, Renfe, is conducting one of Europe’s largest procurement processes, seeking to purchase up to 40 new high-speed trains for a maximum of 1.777 billion euros. The trains are designed for speeds of up to 350 km/h. Following the withdrawal of Alstom and Talgo from the process, Hitachi and Siemens remain as the primary contenders. Renfe requires the first deliveries within 40 months and the full fleet within 78 months.

In contrast, Sweden’s SJ has ordered 25 Alstom X250 high-speed trains, which have a technical top speed of 250 km/h. However, due to current Swedish rail infrastructure and signaling limitations, these trains will likely be restricted to 200 km/h. Upgrading to higher speeds would require significant infrastructure improvements and the implementation of the European Rail Traffic Management System (ERTMS).

Separately, SJ has announced a partnership with Icomera to equip its entire fleet of 20 SJ 3000 trainsets with satellite connectivity. This project aims to provide stable internet via Low Earth Orbit (LEO) satellites, particularly in areas where mobile coverage is inconsistent. The rollout is expected to begin in the second half of 2026, with improved connectivity available to passengers by early 2027.
