GE 44 ton decoder install

Chris,

Thank you for posting the photos and video.  They might be the motivation to install sound is this varmint:

Thanks for posting Chris...can you give the specific LokSound decoder you used. I have my Yoder 44T using a Tsunami, and although it performs well, the sound is not authentic to that particular prototype.

Thanks again

Bob

Very nice project, Thank you for posting.

Bob,

The LokSound Select number is 73444. You can check the sound set on their website.

Matt, the Catepillar prime mover might be just right for that critter. You might also consider a 'galloping goose' sound set, for a gasoline engine.

BTW: I cannot figure why the Quicktime video clip is so low res. Next time I'll try the HDR mode when shooting.

That's awesome. Great sound for such a small speaker. I also have the Sunset 44-tonner and was wondering how to handle command-control operation. Will it also run on DC with the decoder installed?

Matt,

the decoder should be dual purpose, DCC and DC. I have not configured that yet, or the rest of the decoder settings.

I learned a while ago that sound quality is directly related to the enclosure the speaker is in. The speaker itself needs an enclosure at least equal in volume to its size, to eliminate back pressure wave cancellation. Then the engine body should be sealed well except for where you want sound to exit, to have a good sound chamber resonance.

On the sunset model, all the cab windows were covered. I took out the middle side panes, plus drilled open the exhaust stacks. There are mesh covered openings in the hoods.  Fortunately there are openings between the cab interior and the hoods to allow sound to travel. The difference in tonal quality with the body off versus on is dramatic. Bass and mid-range tones really come out once the body is on.

Bob, does your 44T have 2 motors like the Yoder 45T?  I had one of those and the only way I could get it run smooth at crawl speed was to instal a 2nd motor only decoder and consist them.

 Great job. I like the sounds.

I wish I could get sound into the Lionel Trackmobile, like your 44T has now. I forgot all about it until I saw your engine. It's in a box until I figure out how to two rail it or lay some three rail down.

Chris,

If I were to leave the   interior out of my 44, I could add just the sound in it, using  Loc Sound with out the DCC  motor control.  I will check  to see if sound only is available..
