Dapol Jinty

[RomneySands]

I have a Dapol Jinty. It is now over 6 years old. It works just fine, smooth runner etc, etc but it really annoys me! It sets off along my  15' of end to end railway and after about a metre, the loud chuffs, etc, etc subside to quiet ones and it continues this until the end of the layout. Slowing down and speeding up make no difference. If I stop it it starts off just fine and then repeats the process.  I have played with all sorts of CVs until the cows come home. I have tried factory resets, CV 8 = 8. I can turn the sound up or down but always it goes to back to quiet coasting chuffs after a metre of perfection!. There surely must be CVs that can rectify this? My other choice will be to sell it but this is not fair on who inherits it!  I also suppose that I could have it reblown. Originally I bought if for a 4' long layout and it ran on this for four years and I did not not notice this. All ideas, suggestions greatly accepted. The decoder is a Zimo with a Digitrains sound file. Thanks

Sorry, the Dapol Jinty is O Gauge. I expect you all know this but thought I had better add this information.

Increase the value in CV282 to extend the duration of the loud chuffs.

Or, increase the values in CVs 275 &276 to increase the volume of the quieter chuffs.

Or use a mixture of the above.

Thanks very much Paul. I will have a “play” with those CVs during the day and report back. I discovered the dewatering CVS about a year ago but only usually try changing CV272 and CV273 as I like locos that sound as if they are doing something before they move. I’m convinced this happens in real life. I was not sure what 274, 275 and 276 did.

Paul, even more thanks! It is now working perfectly for whatI want it to do on my layout and my ears. It is amazing what I am able to do if I have the correct knowledge and a bit of guidance. Thanks again.
