History

In August 2023, Northern issued a tender to acquire a contract for up to 450 new trains to replace the older rolling stock in their fleet. ^[2] A more detailed tender for up to 329 new trains was issued in 2024, ^[3] and in January 2025, it was revealed that Northern had shortlisted five companies to build its new fleet - Alstom, CAF, Hitachi, Siemens and Stadler. ^{[4] [5] [6]}

Contracts are expected to be awarded in 2026, with the first units delivered by 2032. ^[1]

In September 2025, Modern Railways reported that the TOPS number 781 is reserved for the planned new BEMU fleet. ^[1]
