Sad the 321 at Harwich did not work out. Seems to find a good use for mk3 based DMU or EMUs is limited.
I believe the Renatus units are under the wires and kept warm for possible future use. Whether any conversions to parcels/freight carrying of the units at Wolverton will happen is unknown.
The leasing system where good refurbished units are withdrawn before the end of useful life is daft.
I can't find any updates from Eversholt about the Renatus units, the plan for hydrogen conversion stopped in favour of new hydrogen powered Alstom Aventuras (but no new trains have been ordered), the plan to work with Vivarail for battery power has also stopped as Vivarail went into admin.
The last update was a year ago!

Possible Eversholt may see how GWR get on with the Ealing trial before making a decision on 321 battery conversions to replace old DMUs,
Eversholt Rail and Vivarail are committed to supporting the UK Government’s ambition to decarbonise its rail sector by 2050, and the Scottish Government’s objective of doing so by 2035. This proven and reliable fleet is an excellent fit in terms of characteristics, fleet size and availability for conversion to a Battery Electric Multiple Unit (BEMU).
the Scottish deadline is still 12 years away!
