Some may remember the topic here a couple months ago about the GE 44 ton and  the options for installing a DCC sound/control decoder.

I recently finished the installation of an ESU LokSound Select decoder into a Sunset 44 ton engine. I choose the LokSound Select because 1: it had the proper Cat diesel sound set, 2: it is of small size and has enough amp rating to handle this O scale model.


Here are some photos illustrating the installation:


First shows an overall view with the decoder on the left center and speaker right center.

Finally a quick iPhone video of it in action (I hope this works!):


I have yet to do any fine tuning of the decoder. Bell rate, volume, etc. On of the neat things I like about the LokSound is the ramp up and ramp down of the headlight(s) brightness when turning on and off. It looks just like a real incandescent bulb. Before the install, under DC it would take some voltage to get 'er moving. With the decoder she starts going at speed step one, at less than walking speed.

Also, this model has very little run time on it so the chain drive is a little bit noisy until the chain loosens a bit.

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.




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.
