I continued the work on the mainline section below the mine run with some rock painting.

First pass is a to highlight some spots with a raw sienna and ocher to mimic some color variations caused by nature.
In the second pass I applied a dark umber wash to some deeper spots and rock seams to get some sharp outlines.

Final wash is a dark grey color to finish off the rock color.
