On a recent visit to the A.P. Webb depot in Stafford (August 2022), I came across what looked like a Rail Ability converted ballast plough at the back of the yard where all the buckets and trailers were kept. It had no RRV number on it and no details on the builders plate. It appeared to have rail wheels. It was in deep undergrowth, so could be easily missed. I will upload a photo. Any help on identifying it would be appreciated. Many Thanks. Matthew.

Hi Vince, Thanks for the update. It never occurred to me to look at Rail Ability attachments. I took another look at close up picture of the builders plate and definitely nothing on that. It would be great to get some further confirmation on this attachment.
