I found an old Sony Walkman sitting in a drawer. Bought these cheap speakers (- https://www.amazon.com/Compute...words=small+speakers). Placed Velcro sticky tape on their backs and positioned them under the layout in front of my city area. . Then I used an online YouTube to mp3 converter and copied these city sounds - https://m.youtube.com/watch?v=LZbEIxhiJRM
I burned them on to a cd. Now I have excellent city sound effect sounds when running my layout. Funny how an old useless Walkman CD player can be repurposed for the train cause! I’ve always wanted to purchase a city sound, sound card for the layout. Now this is so much better, since I can burn cds with multiple city sound tracks. Fun stuff. Sorry no pictures, but you can get the drift.
