Simple train sound effect, requires 3 volts DC to operate using speaker, if you are using an external amplifier then you can also use the 12 volt DC input,
however using the 12 volt input will not allow a speaker to be used.
The sounds on the module are as follows:
Steam whistle followed by chug chug of steam train, then rail crossing ding ding, then the sound of a train going by on the tracks clacky clack or should that be Klacky Klack?

Total time to play all 3 sounds aprox 28 seconds.

Messages play one after another, there is no way to select one sound from the 3.
