atom3624 Posted September 9, 2019 Share Posted September 9, 2019 Again, thanks for the insight. It is fascinating, and hugely different from 'just turning a knob' as some may imply! Another 4 months to go and counting ..... perhaps? !! Al. Link to post Share on other sites More sharing options...
Yardman Posted September 9, 2019 Share Posted September 9, 2019 I had working radiator fans on a Deltic I built over 50 years ago. they were run from a Triang x500 motor supplied from a rechargeable battery. 1 Link to post Share on other sites More sharing options...
atom3624 Posted September 9, 2019 Share Posted September 9, 2019 I think space will be at a bit of a premium with this model, in view of all of the additional details .... It would be interesting to see possible 'considerations' .... Al. Link to post Share on other sites More sharing options...

However, as we moved on it became impractical for us to do. However, we have left the mechanism in place for the most part (without motors) so it could be possible for someone with a bit of ingenuity to power them if they wish. Fran Thank you for the information, Fran. I’m just a little disappointed but, of course, still looking forward to my purple Deltic & contemplating a green one. It did cross my mind that with servo-operated pantos on the 92s perhaps the time had come for servo-operated fans linked to the fan sounds. Perhaps when you come to do the 37 (which some people seem convinced you will) it might be easier with only one fan to worry about. There are other single-fan diesels but, on balance, I’d much rather see something which hasn’t been modelled before or has been as badly modelled as Hornby’s 92.

maico Posted September 9, 2019 Share Posted September 9, 2019 (edited) The expensive Marklin Trix use powered fans and they are directional but I suppose there is a limit to what is achievable for £160. Edited September 9, 2019 by maico 1 Link to post Share on other sites More sharing options...

RMweb Gold Accurascale Fran Posted September 9, 2019 RMweb Gold Share Posted September 9, 2019 And people call us expensive! (Not anyone here in fairness!) While prices in the UK market have increased, it is still very good value compared to elsewhere as seen above. Cheers! Fran 1 1 Link to post Share on other sites More sharing options...

The diesel engine was doing what it would have done had there been two, and all 6 traction motors were working, so no strain on them. It just took a little longer to get up to 100MPH as there was less HP available, but once at 100MPH, the engine was quite happy to hold it there. Diesel engines, especially the Deltic ones, were a lot happier and economic when run at high revs for long times, as long as the cooling system was designed for it. I can remember working heavy steel trains over the Marches line with a single refurbished Class 37's hauling 1400 tons. The climb from Shrewsbury to Church Stretton, 12 miles, took around an hour with those type of loads, all with the engine flat out. They never faltered, as long as you could put up with the fire bells ringing every now and then. The biggest limit to the maximum speed a loco could attain was the speed at which the last Field Divert came in, which on a Deltic was higher than other locos. Once the last field divert had done its thing, the point at which the back EMF from the traction motors was matched the output of the main generator/alternator, a locos ability to carry on exelerating was limited. So the higher the speed of the last divert, the higher the speed up to which the loco could keep accelerating. This was shown to me the best when they refurbished and regeared the Class 37's. We had a spell of working 2,000t steel trains out of Llanwernto Dee Marsh with pairs of class 37's. A pair of unrefurbished class 37's could get a 2,000t train up to 60MPH, where the gradients allowed, more often than a refurbished class 37, which had been regeared, thus altering the speed of the last field divert. A refurbished class 37 would start to struggle once above 45MPH. Paul J. Don't forget that a Deltic has the third divert giving it that extra bit of go. Never heard of a speed limiter on a Deltic, had many runs with them with figures in the 110+. Link to post Share on other sites More sharing options...

Directional? That seems an odd idea. The fans are there to push air over radiators; I doubt that they would work effectively if reversed. 1 Link to post Share on other sites More sharing options...

Never heard of a speed limiter on a Deltic, had many runs with them with figures in the 110+. I used to ride with my Uncle who was a top link driver at the + and when rostered on Deltics (although he was a true A4 fan) we regularly topped 100+, only diesels ever bettered that were the HSTs......they were definitely limited but occasionally one was less limited than others......best ever was 134mph..... The worst were the 40s.......especially on empty freightliner stock, rattley front axle up front and rattley stock behind....... Link to post Share on other sites More sharing options...
