SHornby working fans

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

Some the HST 125 variants had fans, but I cant remember which ones..R2701-04 I think.

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!

if it works first time, you did something wrong!

R2645X was one of the Class 56. HSS310 Twin fans

Class 43 HST HSS332 Single and twein fans

R2963X/R3044X are examples of Class 31 HSS361 Single fan X9315

Simple task to look up likely locos and pull their service sheets. The above took me less than 5 minutes.

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.

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.

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. Smile

WTD ........... Nurse, the screens.

You are right in saying that they are no good in there current state, as they do not look realistic. 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.
