Under its Delta 2.0 project Sweden's SJ AB begin procuring Alstom Zefiro Express high-speed trains from Bombardier Transportation, during the 2020s, later rebranded as Avelia Stream Nordic by its successor Alstom.

The SJ 250 or SJ X250 electric multiple unit train fleet is planned to have fixed formations measuring up to 179 metres (590 ft) and operate at up to 250 km/h (155 mph). The trains will use the current and future high-speed rail network in Sweden, in Denmark and in Norway, in temperatures down to −40 °C (−40 °F).

SJ's aim is for these trains to replace air travel between the busiest airports in the Nordic countries—between the Scandinavian capital cities of Copenhagen, Oslo and Stockholm. Delivery of the fleet is expected during 2026‒2028. As of 2022, the planned fleet was for an order of twenty-five trains.
