I've used an old servo board (removes the PWM) to power a buzzer (works well) but it's just not a train type sound.
Any thoughts on a hooter small enough to fit in an O scale unit ?
The best sound board I have found is Adafruit's "Audio FX", it comes in 2 MB/16 MB and mini or standard sizes and with/without built in amplifier. Their 2W mono amp works well with the Audio FX to power a good speaker.

" With 27 MHz which means a long antenna, on both transmitter and receiver.
IF the distance between the transmitter and receiver isn't much, like when you are following the train switching,
neither antenna needs to be very long, 4-5 inches will do.
But if you decide to absorb the goodness of a malt beverage, while watching the choo-choo do it's thing,
you may lose control when the loco gets some distance away from you.
With 2.4 GHz both antenna can be short, and I mean an inch or less."
Quite right and it works well indoors at this stage.
Hope to start garden track some time.
Local fixer upper of RC stuff has standardised on 'FlySky' 2.4 GHz.
He is my source of cheap 27 MHz transmitters and receivers - which helps (pensioner).
BUT now that I've learnt how easy and convenient it is after setting-up the tracks to whip in the batteries and away we go.
I wouldn't mind going for the 'FlySky' stuff when we get outdoors.
