The engine conversion was carried out to evaluate two new types of prim mover ,the Ruston Paxman and the Mirlees Blackstone both in series called the 275 ! They both produced 1800 bhp ! Basically they were marine diesels of a simple straight six . The slow or sluggish acceleration was to max out power before wheel slip! The project never gave life extensions to the class but lead to the development of the Mirlees straight eight of 3100 bhp to be used in class 60s.
Where I live in Tasmania, Australia. We have locomotives with the same EE 12CSVT engines. Its the most beautiful sound. Esp when going up hill and full power.
This 37 has a different engine, a Mirrlees MB275T. Over here in the UK, the normal class 37's have the engine you mentioned, but a fleet of four Class 37 locos were converted to become test-beds for this new engine type - Hence the first Mirrlees loco's name : Mirrlees Pioneer. Nevertheless, both engines make a beautiful sound, although I must say I prefer the Mirrlees sound!
FirstGearSims This one was one of two that where Ruston engined (905/6), the other (905) was converted back to D6836, there are none remaining that have a Ruston engine
Yes, sorry about that, forgot there was the two Ruston engined ones. Although I'm not sure what you're saying about D6839/905 - it is currently based at the Mid-Hants Railway and, whilst "dressed up" as D6836 it does indeed actually have a Ruston engine, so its livery is fictional to an extent. If you check some videos of it there you will notice the difference in sound to a standard 37.
evidently they were called slugs due to a choke in the air line to governor, so as to allow turbo to spool without loads of clag, as in when power was opened up to full suddenly, but I think thats been removed, makes sense considering they produce nearly as much coal as a steam engine needs....

What a handsome beast!
Sounds fecking gorgeous!
I want 37 906, the best sounding 37 ;-)

do these 37 9s with the miralees engines and ruston engines use the same turbos as the regular 37s? cos they sound very similar to the original 37s?
Clag monster 😄
On it
They should make a Bachman class 37901 like if you agree
