Final answer:
A train is the vehicle that runs on a track and blows a whistle. It's a widely recognized acoustic signature of trains and has become an icon in various cultural media.
Step-by-step explanation:
The vehicle that runs on a track and blows a whistle is a train. None of the other options like a Car, airplane, or helicopter typically run on tracks or use a whistle as a signaling device. Trains have been historically known for their distinctive steam whistles, a sound still commonly associated with trains, which began as a safety measure to alert people of the train's presence or approach. The steam-whistle's echo and the solid roll of a train's wheels on the tracks create an unmistakable acoustic signature. This whistle has become culturally iconic, as evidenced in various forms of media, such as the classic Beach Boys song 'Caroline, No' where a train whistle can be heard as part of the song's conclusion.
