In the right conditions, the 50 dub-dub/thud-thud clearly comes through on a 56 under power. Here is a example (from the Roy TheMouth YT channel):It is, running up to 900rpm with two turbos rather than earlier engine's four. Believe CP1800s (Portuguese 50s) only had two turbos as well? The 56s had an element of silencing not that you'd know. If listen to a 56 in a tunnel the typical 50 dub dub sound does come through.
More deafening overseas diesel locos found on my extensive trawls of YouTube....But if we're allowed foreign stuff then...
Yes, particularly so in the crater that is Stratford International. They sound like a swarm of mega bees as they approach.We're not going to mention the almighty roar of the 373s? What a sound.
Ah, the SNCF Class CC 72000's Portuguese cousin. Positively thunderous under load (from the GRIDMASTER6 YT channel):Well if we are gong beyond these shores in our search, may I commend:
Portugal, 1900 class
I think I remember reading somewhere that CP had problems with the exhaust silencers on the 1900s and ended up just removing them... I was walking around São Martinho do Porto some years ago and what I can only describe as 'rolling thunder' went through the town.... I suspect that was a 1900 or 1930 (the railway was out of sight so I couldn't check).Ah, the SNCF Class CC 72000's Portuguese cousin.

Sticking with Portugal, and from the same YT channel, a 1800 class (basically a Portuguese Class 50 for those unaware) under load. Contrast and compare with their British relatives!
Having (once) heard a CSX GE AC6000CW 'in the metal' I can imagine how loud a pair of 6000 hp V16s might be...More deafening overseas diesel locos found on my extensive trawls of YouTube....

Truly feels like an experience when one passes.
Totally agree with you on them been very noisy for a new class of loco, when stood in a station like York you certainly know where it is waiting. In this day and age not something you should have to put up with all the passengers waiting should get a claim in for deafness.If you are talking about noise then the class 68s have got to be up there for a modern diesel.
Judging from the above clip, I can certainly beileve that the silencers were either not working properly or had been removed entirely. 'Rolling Thunder' is frankly a understatement!I think I remember reading somewhere that CP had problems with the exhaust silencers on the 1900s and ended up just removing them...

Here's some Canadian Pacific GE's (4400hp ES44AC and AC4400CW) accelerating away after crew changes in an 'urban canyon' of buildings in Kamloops, BC, filmed around and from the hotel I was staying in:
(No great artistic merit there, but that has been one of my most popular YouTube videos - I'm sure the diesel noise is the main reason )
As you've brought up modern GE power, you might like this one with nine AC4400CWs and AC60/44 convertibles:I think I remember reading somewhere that CP had problems with the exhaust silencers on the 1900s and ended up just removing them...

Pure chance, but the only AC6000CW I've ever seen (and heard!) in the metal is CSX #649 - the second video features CSX AC6000CW #648 (and it makes the SD40-2 in the middle of the set look small...)As you've brought up modern GE power, you might like this one with nine AC4400CWs and AC60/44 convertibles:

Yes, quite, the 90 degree turn at seamer west junction heading towards Filey, sqquueeaaalllll142 on any tight curve, the flange squeal will wake even the deepest of sleepers.
Deltics also take the medal for noisiest shut down, with all of the counter-rotating timing gears between the clockwise and anti-clockwise crank shafts.On the Severn Valley Railway, if you go somewhere like Arley which is a very quiet spot, some miles from main roads etc then I'd say a Deltic is noisiest of all heritage diesels, because of its continuous napier drone, but starting off a class 37 can be deafeningly loud. Out on the mainline at Kidderminster the only locos I can hear inside my house are class 68s, nothing else gets through the double glazing!
Oh yes 185s are noisy I've been on one before @londonmidland. But 220 voyagers seem noisier - maybe due to more power?@SolomonSouth Think you need to come out of Southern land to hear some proper noise
Wait until you hear a Class 68 or a 185 if we’re comparing DMUs.
This. Everything about 180s just screams noisy. The idle noise, the sound they make when slowing down, everything. Their brake squeal makes a 142 sound like feathers rustling in comparison.I have to give a mention to the class 180, they idle loud, full speed loud and they breaks just sound AWFUL when in use.
TPE's Class 68s are ridiculous in terms of noise. The fact that one is actually called Destroyer is all you need to know. Can hear them miles away. Great if you're an enthusiast, awful if you're a resident along a line. On the occasion I have been to Manchester Piccadilly or Liverpool Lime Street when one is sat idling in the train shed, you can hear them around the whole station.
Both have Cummins QSK-19 engines producing 750hp, although I think that the engines on Voyagers have been derated. Maybe the difference in transmissions makes the difference.Oh yes 185s are noisy I've been on one before @londonmidland. But 220 voyagers seem noisier - maybe due to more power?
Surely some WD40 would improve things.
