From Railpictures. Photographer Blair Kooistra says of this photo:
While trains detoured around the south end of the lake via Union Paciifc’s former Western Pacific, Southern Pacific work crews valiantly regained the route across the Great Salt Lake foot by foot in the summer 1986 after storms and high water washed away the railroad. While work trains dumped “armor rock” and gravel from either end to restore the roadbed, it was earth movers and maintenance workers who raised the rock fill and brought the washed-away tracks back into alignment. On the western portion of the lake between Lakeside and Strongknob, a work crew contemplates their next move.
