Whilst the decision on this is ultimately down to the website owner, I do think that the few UK NG loco to plant conversions should be included - there can't be more than a handful out there anyway. Just my thoughts!
In my personal opinion this is definitely a piece of on-track plant albeit a conversion but that is not unique in the business. As such I feel this and others similar should be included in a site called 'ontrackplant'. In fact I would say that it was more worthy than some wagons, trailers and tracked machines. There are several flail machines already on the site though R/R most some sort of conversion. At least this is permanently on rail.The site has moved on a lot from the original objectives but Vince is the final arbiter on these matters so I leave it to him with my views.
Yes, Quattro have acquired the site and totally refurbishing the inside. There are machines on site in the workshop, but mostly used for refurbishing trailers rather than the Cwmbran workshop that has limited facilities.
@Dennis Graham, the power car sections do not operate in tandem as there is no through cabling - there's not even a cab to cab phone! Plus tail lights have to be set by manually switching them over in the rear cab. Each power car can work with either of the other 3 or even on it's own.
It is believed that this vehicle (#184.108.40.206) is the same one that was on display at Rail Live 2019, although no-one who visited the show has come forward with confirmed build details. If it transpires that they are different machines, I will split the record/sightings accordingly.
