This route is based upon the Great Zig Zag railway between Mt Victoria and Bowenfels.
On the 18 Oct 1869 the first official train pulled into Bowenfels Station, west of Lithgow, on the Great Western line from Sydney. The Blue Mountains had been successfully crossed and with further extensions the railway would open up land to the west of New South Wales.
The Blue Mountains represented a significant geographical boundary, as they rose to a height of approximately 3500' (1066m). The NSW Government was pushing strongly for a cheap and speedy way to extend the new railways over the Blue Mountains. The NSWGR explored a number of options to get up the mountains and down on the other side.
In the end two Zig Zags were built, one to climb the eastern side, at Lapstone, and one to descend the western side at Lithgow. This second one was know as the "Great Zig Zag", and was hailed as an international engineering marvel in its day. The Great Zig Zag operated between 1869 and 1910, when it was bypassed by a 10 tunnel deviation.
The Zig Zag lowered the line by approximately 500' (170m) in 5 miles (8 kms) at a ruling gradient of 1 in 42. This was marginally easier then the gradient ascending the Blue Mountains on the eastern side, which was 1 in 33.
When first opened, trains were required to reverse up or down the "middle Road", however this proved to be a dangerous activity, so run around facilities were provided to eliminate the need to do this. Though this added extra train occupancy time to the route and resulted in it becoming a major bottle-neck.
To attempt to alleviate the congestion a number of changes were made toi the Western line between 1880 and 1910, and these included:
- duplication of the lines
- numerous deviations and re-alignments
- elimination of the Lapstone and Great Zig Zags.
This route represents the Main West in the period between 1897, when the Dargans Creek Deviation was built to eliminate some 1 in 33 track between Bell and Clarence, and just prior to the opening of the 10 tunnel deviation.
