These were scenes at Georgemas on the Far North Line this summer as deliveries of pipes for Subsea 7's bundle fabrication facility near Wick got into full swing.
This is the kind of traffic that is ideally suited to rail and scenes like these should be far more common than they are.
The geometric shapes made by the pipes, the trains, the cranes and the surroundings make for very pleasing photographs.
The summer of 2018 has also provided a calm and warm-looking backdrop to what can often be quite wild country.
It's worth having a close look at the bottom picture where Morven (706m) can be seen in the distance, complementing the horizon tree shapes.
