    I am building my son a train table and want to add sounds to it, is there a chip out there that can achieve this? Does anyone have any schematics?

    Thanks,
    Anthony

    There's the SN76477N complex sound generator IC:

    I don't have any experience with this, but it sounds like it
    was made for the sort of thing you have in mind. The pdf
    file linked to in the page whose link I provided above gives
    a schematic for steam train with whistle, which looks
    up your alley.

    There are lots of hits for "model train sounds" on Google. It is quite common to add them. When I lived in PA, I used to stop at Bowser. He bought the Varney molds and made replicas. He has a great shop and model display. He (if he is still alive) was extremely knowledgeable, not like your typical hobby and crafts store. You may want to call him at: http://www.bowser-trains.com/index.htm

    I think that chip has many sounds on one right?

    i recieved a schematic with this chip labelled machine gun sound simulator.

    This prebuilt module can store up to 250 sounds, you load any sounds you like from wave files into th emodule and play each sound with a simple serial command;

    it can also control 8 RC servos so you can control track switching etc all direct by serial interface (like from a PC).

    Forrest M Mims III in Engineers Notebook II offers " Improved steam engine and whistle " using SN76488N & a 741 IC.

    Sadly, the SN76488N has been discontinued for quite a while. Radio Shack probably stopped carrying it about 20 years ago.
