Dargans Deviation
The Dargans Deviation was a section of the original Main Western railway line over the Blue Mountains in New South Wales, Australia. It was constructed from 1896 to 1897 in an effort to ease the grades of the original alignment (1 in 33) from before Newnes Junction to Clarence, with a ruling grade of 1 in 60. Along with a few crossing loops, it enabled much longer trains to use the line. After the construction of the Ten Tunnels Deviation, it was abandoned.
