Single track of the original Ghan railway line in Central Australia, 1970
The vantage point directly over the track suggests that the photographer was likely standing on an old-fashioned step at the back of the last carriage, looking back the way we had travelled.
Very interesting perspective! Looks not high enough to be taken from a bridge, but too high for a person, but that maybe because of the slopes on either side of the tracks.. In any event, a fine image.
