 MISC: As the train approaches the town, the horn blows twice, which  is the signal for starting up. The mandatory signal for a grade  crossing (long, long, short, long) is never blown, although one  clearly exists. When the train departs, the conductor makes a  confused hand signal to the engineer resembling the horizontal  motion that means "stop" rather than the vertical motion that means  "go". The engineer never responds with the "long, long" starting  signal.
