Will flying Scotsmen return to single chimney

I hate the smoke deflectors that ruin the front end
The style of deflector fitted to the A3s was very popular around the world at the time, with a number of European railways adopting it and Germany (both sides) even retrofitting older locos previously equipped with full depth deflectors. Japan used it, and one of the Australian states, just off the top of my head. It was very easy to simply bolt on the sides of the smokebox and didn't overly obstruct access around the front of the loco on the footplate. The main reason it was popular was that it was extremely effective. The other alternative at the time would have been A1/A2 style, but it was inevitable there would have been deflectors of some kind once the double Kylchap had been fitted. The A4s required no such modification on equipping with Kylchaps, as the front end wedge shape was already an excellent smoke lifter. The exhaust and deflector mod was a quick cost effective bolt-on for a fleet nearing the end of its career, to provide some effective backup and keep the product quality up to standard while BR slowly attempted the troublesome changeover to diesel power. It was enlightened and agile thinking by engineers and managers of the time, and the fleet was at the absolute zenith of its performance during this period. Note it was the considerable licensing cost of the patent that dissuaded the LNER from wider fitment of the Kylchap before WW2, although they were already convinced it was a very good thing. During the war Thompson was able to use the exhaust widely in his rebuild experiments and limited new build programme, as by then the patent had expired, and post war, Peppercorn wasted no time in confirming it for all his A1s and some A2s. Flying Scotsman's appearance today captures the heady, emotional atmosphere at the end of steam. A thoroughbred at the peak of performance yet about to be destroyed had it not been for the intervention of Alan Pegler, pictured heroically aboard his steed at Kings Cross on the day he completed purchase. Not only is the appearance authentic, but it is also within more peoples' living memory than any authentic LNER condition. The performance benefits of this configuration also happily fit very well with the rigours of running on the modern mainline railway.
Interestingly enough, A3 60097 'Humorist' was a locomotive selective by Gresley for a number of experiments including the use of a double Kylchap long before it became standard practice on BR(E) and after a number of odd looking mini deflectors she was fitted with 'A1' style deflectors though they look like they are a bit smaller than the ones found on Blue Peter and Tornado.

I thought Ian Riley want to return flying Scotsmen back to lner condition with single chimney
I totally agree with you the smoke delflecters ruin the locomotive I used to like Scotsman but the proper Scotsmen the nrm won't let us see very sadIt will never find a place back in my heart (which it had when I was a kid) until the deflectors are removed, the single chimney returns, it's painted apple green, and numbered 4472. However, as others have pointed out, most of us have little means of influencing these matters.
Absolutely right.I wonder what the designer would want, could he be consulted today?
Personally, I used to like the German-style deflectors on the A3s - they made them stand out from all other British locos - and the actual shape was slightly different to German locos to boot, IIRC. Would have been interesting fitting them to a Stanier Princess, had they gone for a double-chimney version
Anway, back to today. If the single-chimney version were actually more efficient, I coould support it - but as it is, you'd be spending money to create a less-effcicient, lower-power locomotive. Bonkers, I'd say. And something tells me HNG would agree. My bet is he'd opt for the most efficient engineering solution. I mean, would he want to revert to the 1920 design, back to the short-travel valves, just because that was the original arrrangement?
LNER apple green single chimney running
I can't understand why anybody would want to downgrade a piece of working machinery to an earlier less capable form, just because some people think it looked prettier?
