Class 166 Sound Mod

Class 166 audio incarnate!!!

This pack features 2 key sides:

  • The fundamental soundset recorded from various Class 165s and 166s forming the general expectation of how a Networker Turbo sounds.
  • And 3 unique subsets to pick one from for the interior - one of the Class 165/0, one of the Class 165/1, and one of the Class 166/2... all three sound different and this has been captured.

There are 2 extras in this mod:

  • One file makes the screaming aircon quiet using different recordings
  • Another file overlays sounds mimicking original 1990s door chimes used for the Networker family

For the best experience, follow the installation instructions. These have been rewritten. Any changes I make to files or this mod will be documented in the included changelog text files.

Here is the promotional video from 2021:

Enjoy the feel of Turbo power!

Hi will you be making this compatible with the new steam version 4.26? This sounds amazing and id love to be able to drive with these & the 43 sounds. But my tsw2 mod program is showing that its incompatible with the game version.

Thanks for the update to steam 4.26 version :) however I feel like the interior sounds are just a bit too loud. You can barely hear the horn both inside & outside over the sounds of the engine. I dont know if this is true to life as ive never heard a 165/6 in person.

Love the sounds though 😁

Hey, really like this mod, but i've noticed that the in cab whine is pretty loud... like tinnitus almost. Is there any way to lower the volume of that...?

It's not cab whine, it's HVAC. And it's just as loud as that in real life.

And I can't just have one because if you look at the figures for how many people have download each different mod, it demonstrates their desire to each have different sounds.

This mod is superb. Engine sounds are spot on! Only thing I think needs some improvement is the horn. Just doesn't sound right to me, especially inside the cab. Great work though keep it up :)

it sounds very scratchy to me and doesnt sound like any horn ive ever heard, other than that the rest is great

Too bad. It's recorded from a real 165

The issue here is that it is recorded from inside the passenger compartment of the loco rather than from the outside. It sounds vibrational / distorted from inside the passenger compartment but as you’ll hear from this video, externally it is a MUCH cleaner type of sound. So technically this isn’t actually an accurate representation of the horn.

Doesn’t bother me in the slightest as I don’t use any of your sounds. I was notifying you of your error, so that you could improve the quality of your mods for the experience of others.

Thanks for this, the audio sounds great and makes the 166 much more fun to drive. How would you like a challenge? Removing the terrible 'depth of field effect' in tsw2 which blurs either the cab or the track, or even both if you are unlucky with your scrioll wheel settings! lol
thanks again

You have done God's work here. Thanks! It's like Armstrong Powerhouse sprinkled some dust and it sounds like a real thing. Just a question. You didn't happen to pick up much flange, wheel rubbing, that sort of stuff?

Is it possible to make the horn louder? it's too quiet. loud like the door closing beep

I take it that SoundMod26 is all that is needed for TS4. Or will the other options from the Zip file be needed?

Avatar of ItsYa165
ItsYa165 16 Oct 2023

The zipped files are old (TSW3)

Concerning this, are your recently updated sound mods working too in TSW3? All are marked as only TSW4 compatible and don't have old files, like this, in their download section. Thanks a lot for your impressive work!

So the others are the rule. Ok. May I then assume that new versions not including TSW3 specific files are working in TSW3 too, despite the "TSW4 only tag" in their descriptions? Thanks a lot.

Omonyo 21 Oct 2023

My assumption seemed to be right. Tested your new versions and all working perfectly in TSW3 too, Many thanks again for your work and for these superb mods!
