Lol, that aerial pic is obviously from a few years ago.
They had.
1 off class 31 - pretty well robbed as it had been used as a spares source for other 31's for many years.
2 off industial shunters - used to shift pot ash about when working, built like brick shite houses with 6 inch thick buffer beams, a Rolls Royce diesel engine and a nice household consumer unit as a fuse box plus household rads for cab heating!
2 off 08 Shunters, ex EWS, looked ok as all rods were still fitted and none of the cranks had slipped.
Loads of bits of class 56's about, a few EE V8 and V12's (including a rare one which would have had an alternator as it had starter motors fitted)
1 off Class 47 - cant remember the number but it was a 474xx, this was being cut up with no 1 cab already removed (they are aluminium so worth good cash!), the roof and sides from the engine compartment removed also......given a 47 is a stressed skin build, this results in the main bed bending until its belly touches the rails due to the 32 ton power plant inside!
And the one we went for.....a rare opportunity in preservation as this had been main line running until, whilst parked in a siding in Gloucester, the pikeys robbed the cooper out of it (they also took half of the cooler group elements and some instruments......so maybe it wasn't pikeys!). Most times you get to recover parts, the loco has been sat in a siding for 6 years and used as a donor!
And yes, it was Thompsons, and no, you cant get in without knowing the right people and booking ahead.
