In March 2021, Eversholt announced its intention to convert 321334 for use as a parcels train. In July 2021, Eversholt and Wabtec revealed 321334 in the Swift Express livery. If successful further units could be converted. In November 2021 it was announced that 4 more Class 321s would be converted to Swift Express, with the first of these units expected to be delivered in February 2022. In 2022 it was announced that an unnamed customer had secured its first unit. The final 2 units to be converted are expected to be finished in September 2022.


Battery conversion

In 2022 it was announced that Eversholt and Vivarail are working on a design to convert 321s to battery units that could last up to 30 minutes on battery power.

. The details of the conversion project, dubbed 'Breeze', were published in January 2019, with an expectation that units could be ready for service in 2022although this later slipped to 2024. In November 2021 Alstom and Eversholt announced that they had decided to switch their primary focus to developing a hydrogen-fuelled variant of Alstom's ''Aventra'' EMU, on the grounds that the pool of convertible Class 321 units was too small to support the market they envisaged for hydrogen-powered trains in the UK, and that the Aventra's advanced technology and reduced requirement for routine maintenance were advantages in both manufacture and operations. Although the companies stated that they would maintain the "option" of converting existing trains in the future, the Breeze project was ended in the first half of 2022 and at least one of the Class 321 units selected for conversion (321448) was sent for scrapping.
