QuoitsPlayer Posted March 8, 2020 Share Posted March 8, 2020 Hi everyone, having watched C5's programme about the NYMR on Friday the commentary kept repeating that their 9F was "the only one in the world". Obviously other 9Fs are in existence so is there anything particularly unique about the NYMR 9F? Link to post Share on other sites More sharing options...
RMweb Gold Worsdell forever Posted March 8, 2020 RMweb Gold Share Posted March 8, 2020 The only one with a single chimney, probably means it's not quite as good as the other 8 preserved ones. 1 8 1 Link to post Share on other sites More sharing options...
Steamport Southport Posted March 8, 2020 Share Posted March 8, 2020 The only survivor with a single chimney. That's the only thing really different to the others. 92085 was also a single chimney example but was scrapped at Barry in 1980. Jason 1 1 Link to post Share on other sites More sharing options...
Sheffield Posted March 9, 2020 Share Posted March 9, 2020 You can not take seriously what is said on the television. They also said the 9F was the most powerfull loco built in Britian. I don't think they bother with research any more. 2 Link to post Share on other sites More sharing options...

PenrithBeacon Posted March 9, 2020 Share Posted March 9, 2020 I'm not convinced a double chimney would increase the power, but it would lower fuel consumption. But then again an a heritage line with low speeds and lightweight trains it wouldn't make any difference at all! 1 2 Link to post Share on other sites More sharing options...

I've seen mention that conversion of a single chimney Gresley to double is worth around 500HP. Not sure what other mods were made at the same time - double kylchap blastpipes but were they single kylchap before? The commentary on the program does my head in.

From what I've read, it did raise the maximum power output, which wasn't noticeable for most duties, but did INCREASE the coal consumption at lower outputs, so were less popular with firemen.

Our reply to the TV when the next exaggerated claim comes on, or something silly (in my view) happens is; “that’s for the cameras!” Leaving that aside we enjoy it. Back on topic, we were at the NYMR when they were filming the 9F sequence in the shed. It was in light steam, separated from its tender and the film crew were on the ground.

Denbridge Posted June 1, 2020 Share Posted June 1, 2020 People might knock the programme, but it does nothing but good for the NYMR and wider preservation. Sure, the description was rather vague, but being the only preserved single chimney 9F Makes it unique. So they weren't wrong. 1 Link to post Share on other sites More sharing options...

Though that's the first time I've heard about double chimneys increasing consumption at low outputs, it sounds feasible, if they dropped off the efficiency curve for the drafting, and didn't pull the fire as well as a single. As 9F's were built to be driven hard, I suspect it was seldom an issue in their operating days, and reduced coal consumption at higher outputs, was no double more desirable on the whole, than increases at low outputs. On the same vein, I think that there would not be much difference in performance between any of the 9F's at sub 25mph due to the draughting (drafting?) and any variations in performance would be more likely down to locomotive condition, firebox, tubes, passages, valves, pistons, valve timing etc rather than how many pots it has on top. Re. the 9F being the most powerful, contentious comment as it was (and I suspect just to give some drama to the commentary) it depends in what context you define as most powerful I guess, hauling an express over Shap for example requires a markedly different "powerful" locomotive, to one which hauls Iron ore trains from docks to Consett, or 2000 plus tonnes at Foster Yeoman, the DBHP/IHP etc. figures are probably not even comparable. however.............. given the 9F's could hit 90mph, if there was any one locomotive that could haul an express up Shap, and drag and slog a heavy freight train up a steep incline, I would like to suggest it would be the 9F. Also, I've shouted at the TV so many times whilst watching that TV programme, my wife is concerned for my mental health, but it is a programme that is largely targeting non-enthusiasts, and that most definitely is a good thing for luring new folk into the fraternity, even if it does drive the rest of us nuts! Stuff like Shed and Buried does the same to me, particularly when they rope in "experts"................

[...] It's been my contention for at least the last two decades that the 9F was by far the most successful mixed traffic engine built in the UK, an argument let down by the fact that non had steam heating. 1 Link to post Share on other sites More sharing options...
