    Preserved in its final state, eventually have a crowd-funded project to cosmetically restore to 10000.

    77014. The last engine that hauled a train on the Southern Region at the end on the 9th of July 1967. A engine remembered by a number with fondness and would be a extremely useful machine on today's preserved lines.

    Dial the machine back to November 1949 to save GWR Saint class 2903 please.

    I'm thinking light engine trials....

    I'm not so sure about that - I pass through Mytholmroyd regularly, that's always a trip back to the 50s/60s. Unfortunately it's the 1750s/60s!

    Why only a cosmetic effort? If you are going to dream then dream on a grand scale. Go back to the original but finish the design modifications that were found to be necessary when the machine was undergoing testing.

    The original boiler actually outlived the loco by a good bit, not being scrapped until 1965.

    As Steve intimates, the boiler was never the problem. The issues lay elsewhere. Once a double chimney was fitted and the auxiliaries were modified she was nearly there.

    Her rebuilding remains an interesting piece. As rebuilt she became in theory the most powerful passenger locomotive in the U.K., tractive effort wise.

    Used for London-Leeds expresses in her later life, I remember my late grandfather pointing to her picture in a pocket book and lamenting her scrapping. She was well thought of, by enthusiasts, but perhaps a mixed bag by crews and engineers. The best streak in theory but being a one off put paid to any development.

    First I wish you a Merry Christmas and trust that you are in good health.

    The boiler originally fitted to 10000 is an interesting subject. According to the company records it gave very little trouble. For decades writers voiced the opinion that this was not the case. Where did this view originate from and why was it perpetually regurgitated? I raise this again because I would like to know.

    It took a long time to identify the problem of inadequate steam supply to the steam manifold. The reputation for poor steaming is down to there being insufficient steam to operate the injectors the same problem would tarnish the reputation of any engine not fitted with feed pumps. The problem was solved but people only remember the tarnish.

    The h.p cylinders needed further work. Cast iron was an unsuitable material because of the high steam temperatures. They may have tried steel towards the end - I need to access my books. The design should have been fully reviewed in the light of newer thinking. Blame to be ascribed to a certain French hero of mine.

    The test logs reveal that the hp steam chest pressure lagged the boiler pressure and not by just 5 or 10 psi.

    The successful attention to material and lubrication issues plus a better understanding of the hp steam circuit would have delivered a satisfactory experiment.

    Don't think that we could get away with a new build on this one though. Hope the very thought has not triggered Christmas indigestion for some forum members.

    Interesting comment about the cast iron cylinders not being suitable because of the temperatures. Why was that? I can't see steel being suitable without a liner and, if so, what would it be, if not cast iron?

    Seem to recall there is quite a bit in those nrm archives about 10000. Perhaps there was concern after Schmidt boilers on Fury and in France had caused high pressure accidents. These boilers did not lend themselves to the British loading gauge and were really more suited to boats. The rebuild? Come on Darlo Loco Works lets see this next!

    For me it'd have been a Grange, with a Hawksworth County a close second and an 82xxx 2-6-2T in third.

    It was only when I got to this post that it suddenly dawned on me that people weren't discussing the Ivatt diesel

    What was it used for, or did it just lie around?

    It was used as a source of steam for pressure testing at Darlington Works. See http://www.abrail.co.uk/SBPhotographs.htm and scroll down to Stooperdale boiler works.

    An interesting website to scroll through.
