Right, time to set the info straight.
Basically, when the first south yorkshire transfers came down, 33099 suffered a very heavy engine malfunction, causing in the engine being removed. It has been sitting at Taunton for ages and ages now, I got told by my mate that it's been sitting there awaiting the decision upon its fate.
If it has gone to Camborne, they will most likely repair it up as they need as much as they can get in service at the moment. 30874 & 30876 were both out of service at one time both requiring new engines, and spare ones were not that hard to find, so 33099 is most likely going to Dan Shears for repairs and not disposal.
In other news, 53154 is in need of a serious seat re-trim and interior re-do, as it is very torn up on the inside, floor is immaculate though apart from a few cracks.
The loaned vehicles for rail rep should be going back soon, and by the 1st of April you should see a lot of the older batches of presidents going away, and it'll be the same with the ex Connex nimbuses.
The only examples that will stay are the V---LGC batch, and 42358. (LN51/LK51/LT02/LT52/LR02 batches count as newer versions, they will obviously stay)
The Cheetahs are said to be going to dan shears for disposal once all the branding has been taken off etc, though I think they will be scrapped, as the interiors are very worn out, same with the body, dents everywhere.
Also, good news for 34198! She is being preserved after disappearing from Summercourt at the end of 2017, the same fate awaits 32045
News is still unknown for 52554, again still at Taunton, I've asked my mates about the vario and nobody knows what's going on with it, possibly awaiting for the book value to diminish then scrap?
--Edit:
@richw was correct, it is having a new engine installed and it is being readied for service, cannot wait to see it out and about after languishing for three years!
