Can anyone help me to help an old friend with his many train layouts, please
I know nothing about model trains so I'm unable to help him in his quest for a Diesel HORN sound generator. (They all do sound different as well !! so I am told)
He says he isn't into DCC (electronics?) and would like to hear the horn sound from under the layout, when he presses a button. He has tried tape recorders but really wants sound on demand. (anything in the pipeline FLJ?)

Any comments would be appreciated. I've seen his layouts and there are five in different rooms. Yes, he does live on his own. A veritable train heaven. Almost got me interested but I've got enough on my plate, keeping my boats afloat.
Web site info would very helpful as I've tried and got confused with the steep learning curve.
Thanks everyone.
