Found these on U tube. I have been looking for sometime for radom train sounds that sound good on a great stero. http://www.youtube.com/watch?v=QURWYEj4lgo&NR http://www.youtube.com/watch?v=0C__MJk9PPI&mode=related&search= I use my setero with the Computer and recored the sounds on my Yamaha K-700 with metal tape. Crank up the Adcom Amp’s a little, throw in the NHT SA-1 amp and supwoofer and it sounds like I am track side! My wife on the other hand does not like it, so it must be good! 
I all so found some garden rail road stuff. http://www.youtube.com/watch?v=bBPUyujPoNY&mode=related&search= http://www.youtube.com/watch?v=BwnenfpO5xc&mode=related&search= http://www.youtube.com/watch?v=UCGzKyshzD4&mode=related&search= Sound is OK at best, but seems I have a bigger yard than garage. Hum, might be something to look into next summer. hope you folks enjoy. Cuda Ken
Do a copy and paste to see the videos. Seems the new and soon to be removed Internet Explorer 7.0 is why the links do not show up on the message. Cuda Ken
