RMweb Gold Phil Bullock Posted March 31, 2019 RMweb Gold Share Posted March 31, 2019 Sounds similar to the NBL 43 sound file from Howes - which it should as same engines and transmissions - but I am not convinced by either! Phil 6 Link to post Share on other sites More sharing options...

Geoff Endacott Hi Geoff Erm, both 60° V12 yes, but thats about it. The Maybach is a much more sophisticated engine with dual OHC (4 in total) with 6 valves per cylinder and roller bearing crankshaft. Where as the MAN L12/V18 is a much more basic engine with valve timing controlled pushrods driven by a single cam. difficult to be precise as only very limited YouTube MAN engine sounds. But completely different to a Maybach I think. Regards Link to post Share on other sites More sharing options...
Geoff Endacott Posted March 31, 2019 Share Posted March 31, 2019 I am simply going by the fact that I found it difficult to tell the D800 and D833 Warships apart, but then I was only 12 years old when the last of the NBLs was withdrawn.

Baby Deltic Posted March 31, 2019 Share Posted March 31, 2019 (edited) The CD Diesels Through The Decades featuring recordings by Peter Handford includes Blue Pullmans which were essentially a train with a pair of class 21's at either end albeit in a different form. The MAN engines definitely have a deep note similar to a Hymek when they are under power. (The same recordings are also used in the Blue Pullman clips of the Diesels & Electrics On 35mm series DVD's with John Huntley) They appeared to have a softer note when not under power as in the clip of D600 leaving Paddington 8 minutes into the video below. There's also a shot of it passing at speed 7 mins in but its hard to make out the sound as its too brief.

Geoff Endacott This is a difficult judgement to share because of the passage of time since both types worked the West of England main line in the early 1960’s.At that time I was fortunate to observe both types of Warship at work from a vantage point of Bristol TM.So here is a “value laden “, if you like ,observation to the effect that there was a clear difference between the sound print made by the Swindon built Warships and their NBL counterparts.Sorry if that confuses the issue.

Baby Deltic Posted March 31, 2019 Share Posted March 31, 2019 Its a shame Dapol glue the windscreen wipers in so solid on their class 22's and D600's. It makes it impossible to re-position them without having to cut them off and carefully re-glue them. Link to post Share on other sites More sharing options...

D602 WAS an early repaint, as it received the short-lived chromatic blue. I was with a friend when he photographed it at Lostwithiel in blue/SYP - just about the only picture of a blue D6xx working that I've ever published. I'll ask if he has the actual date but it is likely to have been 1965 or 1966 as that's when we visited Cornwall. Judging by the 5C53 headcode, it was this picture that Kernow used in their research. By 1967 Swindon would have been well into full yellow ends - SYP on blue was short-lived. (CJL) Edited April 1, 2019 by dibber25 2 Link to post Share on other sites More sharing options...

RMweb Premium 7013 Posted April 1, 2019 RMweb Premium Share Posted April 1, 2019 I suppose it boils down to one question. Are there sufficent sound recordings of the D6xx class locos, or locos that used the same engines/transmission to produce a reasonably accurate sound decoder? If not then its always going to be a approximation/ near as damn it. 1 2 Link to post Share on other sites More sharing options...

My model has a double sugar cube speaker by zimo. Judging by the feedback I think i need to turn the volume down. Also i discovered that if i am more aggressive with the throttle, the engine revs before setoff. Throttling back then ensures a gentle start but with the high revs. 1 1 Link to post Share on other sites More sharing options...
