Klu Klux Cut was a curve to the right for northbound trains. Since in the F3 photo the track curves to the left, that train was southbound. This is further confirmed by the telephone line on top of the hill which would have been on the east side of the track, and this view was taken looking north.
In the Dolzall RS2 photo the track curves to the right, and we know that train was southbound, again confirmed by the telephone line in the distance, again taken looking north, so the two curves are opposite each other. / Ron
