Hi, is there any update on when the Bedwyn’s will move over to 800’s please?
No, the modified 802 is still being monitored in service to establish whether the modifications have been successful
An (informed) posting on the WNXX forum appears to suggest they will run with train managers rather than DOO initially.
There are LTP paths in open data feeds to show how IETs will operate these services at some point after the May timetable change, perhaps even from 20 May.
Taking 26 June as an example as the timings seem to be different in the first week or so.
3K03 0401 London Paddington to Bedwyn appears to run as a 10-car, dropping a unit at Reading for 2K22 0515 Reading to Bedwyn and going on to work 1K03 0538 Bedwyn to London Paddington

3K05 0435 London Paddington to Newbury also runs as a 10-car, again dropping a unit at Reading for 2K24 0549 Reading to Bedwyn and going on to work 1K05 0609 Newbury to London Paddington

That basically sets up the Bedwyn services for the day although it does seem to mean that there are some Reading to Newbury / Bedwyn stoppers which are IETs as well. 1K05 0609 Newbury to London Paddington of course goes on to work 1D15 0721 London Paddington to Oxford as noted in 'Siemens Staines' incredibly useful diagram posting on the previous page. The other three units form the Bedwyn services on a 3-hourly round trip.
As 'JN114' correctly indicates, take this with a ladle of salt but it does seem that using 800s to Bedwyn isn't far off. Interestingly, there is a 1K37 0006 Bedwyn to London Paddington which runs into Paddington ahead of 1P51 from Hereford. The unit which runs evening shuttles from Newbury to Bedwyn appears to remain as a Turbo.
