Theengineshed Posted March 5, 2018 Share Posted March 5, 2018 Hi everyone,Don't know whether this could be directed at hornby HQ or whether you guys (and gals) would be able to assist.I'm trying to find out the exact number of diesel locos that hornby have put into production, which have either a single or double working cooling fan on them.I know the class 56 has a dual fan arrangement, but there's very little info out there, to give me more models with this feature.If possible, I'm looking for the model code of the loco with this feature, so that I can source them for a little project I'm working on.Whilst on the subject of diesel cooling fans, can anyone tell me whether the dual fan arrangement on the actual loco, work individually or as a pair?Any help would be apprciated Link to comment Share on other sites More sharing options...
Peter in Oz Posted March 5, 2018 Share Posted March 5, 2018 Some the HST 125 variants had fans, but I cant remember which ones..R2701-04 I think. Link to comment Share on other sites More sharing options...
2e0dtoeric Posted March 5, 2018 Share Posted March 5, 2018 I understand that they were driven by an elastic band off the motor drive-shaft.This wasted motor power, and after a while, the band deteriorated and made a lot of noise! Link to comment Share on other sites More sharing options...
trainlover23 Posted March 5, 2018 Share Posted March 5, 2018 Don`t bother they are a waste of time and just a gimmick Link to comment Share on other sites More sharing options...
96RAF Posted March 5, 2018 Share Posted March 5, 2018 R2645X was one of the Class 56. HSS310 Twin fansClass 43 HST HSS332 Single and twein fansR2963X/R3044X are examples of Class 31 HSS361 Single fan X9315Simple task to look up likely locos and pull their service sheets. The above took me less than 5 minutes.Rob Link to comment Share on other sites More sharing options...
Theengineshed Posted March 5, 2018 Author Share Posted March 5, 2018 Thanks for the replys guys.I'm not looking into buying them as a feature, more of a way of looking into getting one, (or a couple) for a project to improve the initial design, as I was aware that the hornby design has flaws with respect of the direct drive to the motor pulling to much torque from the loco thus lossing it's power.

96RAF Posted March 5, 2018 Share Posted March 5, 2018 You could probably motorise them using tiny motors found in phones and small r/c stunt cars - usually less than 6mm diam by 12mm long. The phone vibrator motor is about half that length and even less diam. Link to comment Share on other sites More sharing options...
walkingthedog Posted March 5, 2018 Share Posted March 5, 2018 In OO scale they are a total waste of time. You can’t really see them unless you are looking from straight above, very unrealistic. I disconnected the one I had, can’t even remember which one it was. 😀 Link to comment Share on other sites More sharing options...

But imagine if a loco with proper fans and a custom smoke generator was sat in a siding on an ehibition layout (or even at home) with the fans running, smoke being generated from the exhausts and sound (especially from a cold start) and I'm sure you'll agree this this would be more of a wow factor, as the there is something happening on the layout instead of "dead air".This is what I'm working on at the moment, hence the original question regarding dual fans on a loco spinning independently or together.

Don’t like smoke (makes the layout smell) or sound (can be very annoying) in OO. O gauge and above is just about acceptable. Link to comment Share on other sites More sharing options...

ellocoloco Posted March 7, 2018 Share Posted March 7, 2018 Hi Hornby might have only put the band driven fans in their OO locos but they have improved on this in some of the International models. I have a number of the Electrotren ALCo 316s and these have the band driven fan - as does the similar ALCo 318 type. When Hornby launched the (again) similar ALCo 321 they replaced the band driven fan with one powered by a micro motor. This can be operated seperatly under DCC and links to the ESU Loksound that is factory fitted. This is a much better set up than the band driven arrangement. Look at the service sheets for E3115 for the micro motor fan and E2413 for the band arrangement. These have been available as spares - try Lendons website. I am surprised that the micro motor has not been incorporated in later Hornby OO locomotives, but as many of the comments reflect, it maybe seen as an unnecessary gimmick. I quite like it, but it does need the DCC off switch at times..... Best of luck with your project Link to comment Share on other sites More sharing options...
