May I may make a comparison with another loco (but not No. 488 as per my post #1098) - and one which a decade ago would seem an equally unlikely candidate for a return to steam on a former BR(S) line? I'm talking about GWR 2-8-0T No., 4253. Without wishing to drift off into a debate about how appropriate it may or may not be on a former Colonel Stephens line in the South East of England, here is a loco which really was a beat-up wreck. It was one of the roughest engines in Barry scrapyard. Look at the two top pictures here. No. 563 was able to travel some 70 miles up to Waterloo at 25mph at a maximum boiler pressure of 60lb psi after a fairly minimal amount of touching up at Eastleigh (the word"overhaul" would be an exaggeration). This is still essentially the condition in which it is in now By contrast, 4253 would go absolutely nowhere in the condition in which it arrived at Rolvenden. It couldn't have moved an inch under its own power even if you could have got the boiler pressure up to 60 lb psi as so many parts were missing or rusted through! Fast forward to 2017 and the group working on it have made unbelievable strides to turning it into a working engine and according to the latest "Tenterden Terrier", the current estimate for the complete overhaul is about £400,000. True, No. 4253 isn't the only survivor of its class and in view of the state it was in, there will not be the same issues about conserving original as with the T3. On the other hand, while not underestimating the work likely to be needed before 563 runs again, I think the group restoring No. 4253 would have given anything to have started with a loco in the same condition as the T3.
