A safety whistle works as follows:
A safety whistle works by using the force of air blowing through it to create a high-pitched sound. When you blow into the whistle, the air passes through a small opening and causes a vibrating column of air inside the whistle. This vibration creates a loud, attention-grabbing sound that can travel over long distances to alert others of your location or in an emergency situation.

The word 'train' is applied to 'whistle' in the place of an adjective, that is, a word that describes the type of whistle. But have you ever heard a wolf whistle? Many compound nouns eventually run together, like handbook or cupboard, and maybe one day, wolfwhistle.
