This is a tough one from what I've read and my own personal feelings regarding the NRM's collection of engines that will probably never go mainline; when the North Staff New L was bequeathed to the Foxfield I was rather pleased, as since being in the NRM's collection since the 90's it was seemed to jsut have been left in a corner to be gather dust and not really be noticed, especially with the transfer to Locomotion, with the Foxfield it will be overhauled and will more then likely become the jewel in their crown so to speak.
Th T3's a little more difficult to judge, being an engine that whilst not at the forefront of the collection was always rather noticeable alongside the likes of the D17, Midland Compound, SECR D and even Mallard for that matter. The engine's going to a railway which from what I can tell has very little covered storage to cater for it, and whilst I would love nothing more then solid plans for an inspection to see how difficult a task it would be to get a gem of the Victorian and Edwardian era to steam again, I want to know that the Swanage and NRM have thought this through more then just dumping what the NRM considers by this point an "extra" to a railway they think can handle it.
