I know I am not reinventing the wheel here, but I found a sound record/play box and installed in the caboose. I ran the switch out the back window. Found some .wav files online steam train whistle, bell, cow moos and horse whinny's. I have the Bachmann Cow Catcher Train with animated cow car, and I added an animated horse car. Mixed them all together and recorded them. Along with the built in chugging, sounds pretty good! I tried to upload pictures, but it said the box was full.
HI again,
The idea may not be new, but it is great that you are having fun with it. As for pictures, you must use the link to the picture and post the link so we can see it here.
If you have a chance to try it give it a go here.
Best, Bill
Hi Loco Bill! All right, I am trying to post links. Please let me know if it works. Thanks!

Sorry for the late response, but yes the links worked perfectly, and your installation of the sound box looks great. Bill.
