Is it worth making this generator, or can you advise me some affordable chip, or a chip with sound recording and playback.

Not now we have continuously welded rail!Is it worth making this generator,
Not if he wants the sound of a steam locomotive.If you are going to use Max's suggestion, then you need to find a train to record, without being arrested for trespassing on the tracks.
I don't know where he's from: In Britain you don't need to go very far to find a heritage railway!Not if he wants the sound of a steam locomotive.![]()
I remember that device. it seemed so clever at the time!I know this is four years after the OP's post but in case anyone is interested in a fun IC...
In 1980 I put together a locomotive sound generator using an SN76477N IC. The circuit was in the Forrest M. Mims Notebook sold by Radio Shack. It seems these things are still for sale here and there. The User Guide has a couple of train and whistle generator circuits.

That's not the post date, it's his join date. Look below it.I know this is four years after the OP's post but in case anyone is interested in a fun IC...
I also played a little bit with the device. Very interesting and powerful for late 1970s technology. But very fiddly, one had to tweak a lot to obtain the desired sound.I remember that device. it seemed so clever at the time!
