This recording from the New York City subway system includes the classic and familiar chimes to indicate that the sliding doors are about to close. Newer cars have a spoken message, “stand clear of the closing doors please”. The doors open and close at a couple of stops. There’s quite a bit of talking going on in the car along with the track noise, electric motor acceleration, and screeching brakes. If you listen carefully you can hear Ray telling an embarrassing story about how he once fell over onto another passenger as the car took off. Sorry, Ray!
