RMweb Gold RedgateModels Posted October 14, 2009 RMweb Gold Share Posted October 14, 2009 As a Diesel numpty (even though I grew up around banger blue 20s, 37s, 47s and peaks) I don't know which way round my Heljan Kestrel should be when moving "forward", so which is number one end, the one with the roof fans close together or the other?

BrushVeteran Posted October 14, 2009 Share Posted October 14, 2009 As a Diesel numpty (even though I grew up around banger blue 20s, 37s, 47s and peaks) I don't know which way round my Heljan Kestrel should be when moving "forward", so which is number one end, the one with the roof fans close together or the other? Number 1 end is the radiator end of the locomotive, so the one where the roof fans are. Link to comment Share on other sites More sharing options...
RMweb Gold RedgateModels Posted October 14, 2009 Author RMweb Gold Share Posted October 14, 2009 erm, there are fans at both ends ..... Link to comment Share on other sites More sharing options...
BrushVeteran Posted October 14, 2009 Share Posted October 14, 2009 erm, there are fans at both ends ..... Sorry, yes I didn't make myself very clear. On Kestrel No.1 end is the larger area where the long twin roof shutters and wider spaced twin roof fans are. Link to comment Share on other sites More sharing options...
RMweb Gold RedgateModels Posted October 14, 2009 Author RMweb Gold Share Posted October 14, 2009 Righto, cheers for that. I'll make sure my Heljan one runs the right way once I get the courage to follow Bromsgrove Models' instructions and lob a DCC chip in it Link to comment Share on other sites More sharing options...
59004 ( was Shedcombe....) Posted October 14, 2009 Share Posted October 14, 2009 Hi, I'm still trying to find out which end is 1 on Kestrel. In the UK it's indeed normally the fan end ( thus not conclusive to Kestrel ) however, the Class 59's and 66's have the exhaust end cab 1 and the fan end cab 2 !!!!

Guest D.J.K. Posted October 14, 2009 Share Posted October 14, 2009 Sorry, yes I didn't make myself very clear. On Kestrel No.1 end is the larger area where the long twin roof shutters and wider spaced twin roof fans are. I'm glad someone asked this question. I was wondering myself.... So out of interest, if the Rad fans and shutters were at No 1 end, what were the ones at the other end for??? Link to comment Share on other sites More sharing options...
59004 ( was Shedcombe....) Posted October 14, 2009 Share Posted October 14, 2009 I bag to differ in opinion here, and think cab end 1 is where the closer space roof fans are. The closer spaced roof fans are where the cooler group is, the wider space roof fans are where dynamic braking cooling and control equipment is. See Kestrel article and drawing Regards, Michel Link to comment Share on other sites More sharing options...

So out of interest, if the Rad fans and shutters were at No 1 end, what were the ones at the other end for??? The larger No.1 end radiator is for the main engine water jacket cooling whilst the smaller No.2 end contained fans for the heat dissipation from the charge-air heat-exchanger and lubricating oil cooler.

BrushVeteran Posted October 14, 2009 Share Posted October 14, 2009 In reply to 59004 and so not to confuse Redgate Models, can I assume he has seen the official Brush drawings? Because I have and my copy of the official Brush Kestrel brochure clearly states which end is which and supports my statement. Link to comment Share on other sites More sharing options...
59004 ( was Shedcombe....) Posted October 14, 2009 Share Posted October 14, 2009 BrushVeteran has the correct info, I was only advising, going by the info within the link given. No need for confusion anymore. No need for such a tone either. I was merely trying to help. Regards, Michel Link to comment Share on other sites More sharing options...
RMweb Gold RedgateModels Posted October 14, 2009 Author RMweb Gold Share Posted October 14, 2009 Thanks Guys, especially BrushVeteran for his authoritive answer.

59004 ( was Shedcombe....) Posted October 14, 2009 Share Posted October 14, 2009 Nah, outside for 10 minutes with the dog did the trick already, but thanks anyway for the offer. Regards, Michel Link to comment Share on other sites More sharing options...

Guest D.J.K. Posted October 15, 2009 Share Posted October 15, 2009 Yes, nice photos and thanks for answering my question...... It's interesting that the roof panel/grill at No2 end that got changed during the life of the loco, is different again on the drawing.... I wonder, is there a photo anywhere showing the early roof panel, with the loco on the modified 47 bogies.... Link to comment Share on other sites More sharing options...

I wonder, is there a photo anywhere showing the early roof panel, with the loco on the modified 47 bogies.... See link below: Kes-pic-1 It seems by the official handover date that the grill had been modified to as Heljan has it modelled. See pic on this page: Kes-pic-2 The Grill was the intake for the engine room pressurising fan. The theory being, (I think) that the engine room pressure would be held at slightly above atmospheric pressure with clean filtered air. This should keep the engine room cleaner and cooler. The main benefit would have meant cooler air being drawn into the engine hence more power. Seems like the Brush/Sulzer engineers must have been playing about with the system throughout the loco's time on BR as that??™s at least 3 variations to that particular intake. Cheers, Porcy Hi mods. I wonder if it may me a good time to merge threads. See. My link Link to comment Share on other sites More sharing options...

I wonder if it may me a good time to merge threads. See. My link Thanks for that Porcey.. I'd been through that website but hadn't picked up on that first pic as showing yet another variation. I think the colour photo at the top of your second link shows the final style grill / roof on the 47 bogies.. So still looking for a clear photo of the Heljan style roof panel with the 47 type bogies.... There's a pic in Toms OPC Brush history of Kestrel actually being lowered onto the new bogies and the roof panel in question is absent... Beginning to think that's when the "final style" mesh grill was fitted.. Link to comment Share on other sites More sharing options...
Porcy Mane Posted October 20, 2009 Share Posted October 20, 2009 So still looking for a clear photo of the Heljan style roof panel with the 47 type bogies.... As posted in the other thread... Big Kestrel Pic Porcy Edited for thick headedness. Misread your post. Disregard above tosh. I don't think you'll find a pic of the Heljan type grill on Type 47 bogies. I've a feeling the grills will have been modified before this and not have reverted back.... Link to comment Share on other sites More sharing options...

Looking at the options then, it's a bit of a mod on the roof, or replace the bogies.... Link to comment Share on other sites More sharing options...

Regards, Michel That's the GM/EMD convention for the 59's & 66's ie the opposite to the normal UK/BR one. FYI Deltics No1 end has some vertical pipes by the left buffer Link to comment Share on other sites More sharing options...
