Ordered in 2017, the trains were originally due to enter service from mid-2019, but were subject to several delays which prevented this.[14] By December 2023, 50 units had been accepted by SWR.[15]
SWR began their phased entry into service from January 2024.[1][16] They will eventually allow the withdrawal of SWR's fleets of Class 455 units and the cascade of the Class 458 fleet to longer-distance services.
