The zig zag closed in 1892 when the Main Western line was diverted via the [[Glenbrook Deviation (1892)|Glenbrook Deviation]] and subsequently sections of the line were repurposed as the [[Great Western Highway]], and later use as a walking track.

==History==

=== Nineteenth century ===
The contract to build this railway from Penrith as far as Valley Heights, which included building the Knapsack Viaduct and the Lapstone Zig Zag, was awarded to William Watkins in March 1863 but was completed eighteen months behind schedule in December 1865. It opened for traffic in 1867.

Once the westbound train had crossed Knapsack Viaduct, it entered the Bottom Road of the Zig Zag. There were points where the Middle Road cut backwards and sharply upwards to form the middle stroke of the Z. Beyond the points, Bottom Road extended an additional {{convert|532|ft|m|order=flip}} to a dead-end. It was in this area that the train stopped before it reversed direction to climb Middle Road. Similarly at the junction of Middle and Top Roads, Top Road continued some distance to buffers on the edge of Knapsack Gorge. Here the train again reversed its direction to resume the journey over the Blue Mountains. Lucasville Station was completed in 1877 on the extension section of Top Road. In 1886 the line of the Top Road extension was remodelled with a new parallel, more steeply sloped line to the west. Both of the lines of the Top Road extension are clearly legible.<ref name="NSWHD 1170821"/>

The line of track (now without rails) goes through well executed rock cuttings on the standard walk along Top Road from Knapsack Street and Skarratt Park. There is a pleasing stone culvert to the south of Lucasville platform. Lucasville station was built in 1877 for the Minister for Mines, [[John Lucas (Australian politician)|John Lucas]] who had a holiday home nearby.<ref name=glenbrook/> The culvert, which is still in operation, utilises a rock-cutting on the west side to divert run-off water deep under the track in a square channel constructed of stone blocks. The water then runs down a steep gully to the east.<ref name="NSWHD 1170821"/> To the west of the Upper Road there is a series of low sandstone terrace walls which probably marked the boundary between Lucasville estate and the railway. The Zig Zag is largely surrounded by bushland, interspersed with impressive views east to Sydney. The setting provides a striking sense of the nineteenth-century journey over the mountains as the traveller was entering into a wilderness. At the southern entry to the Top Road of the Zig Zag, at the end of Knapsack Street, there is a gate to inhibit vehicle access. Just beside this gate, on the northern side, there are four surviving sleepers and metal spikes, all that survives from the original railway track.<ref name="NSWHD 1170821"/>

The rail route across the mountains extended as far as [[Wentworth Falls]] (then called "Weatherboard") by 1867<ref>{{cite web |url=http://www.nationalparks.nsw.gov.au/parks.nsf/parkcontent/n0004?opendocument&parkkey=n0004&type=xk |title=Visiting a park |work=[[National Parks and Wildlife Service (New South Wales)|NSW National Parks & Wildlife Service]] |date=28 November 2011 |access-date=5 December 2011 |url-status=dead |archive-url=https://web.archive.org/web/20061003104633/http://www.nationalparks.nsw.gov.au/parks.nsf/ParkContent/N0004?OpenDocument&ParkKey=N0004&Type=Xk |archive-date=3 October 2006 |df=dmy-all }}</ref> but the Lapstone Zig Zag, which included Lucasville station, soon ran into problems: the length of the top points and bottom points limited the length of trains and the single track meant that trains travelling in opposite directions had to stop at crossing points. The first crossing point after Lapstone Zig Zag was at Wascoe's Siding at what is now [[Glenbrook railway station, New South Wales|Glenbrook station]].

The Lapstone Zig Zag was the first Zig Zag constructed on any main-line railway anywhere in the world. The idea on which Whitton built came from the Indian railways. A friend of his, Solomon Tredwell, had in 1859 started the construction of half a Zig Zag (with a reversing line and stone viaducts) at [[Bhor Ghat|Bhore Ghat]] on the [[Great Indian Peninsula Railway|Bombay to Poona line]]. Although Tredwell died in 1859, his widow saw the half Zig Zag to completion in 1863, employing 42,000 men, and this feat was reported at some length in ''[[The Sydney Morning Herald]]'' on 3 July 1863. Whitton knew of the conquering of the Bhore Ghat, which posed problems very comparable to the Lapstone Monocline, both from personal and public communications. The way in which he adapted the Indian experience into a full Zig Zag, approached over an exquisite, and very cheap, sandstone viaduct, was a substantial feat in world terms of railway engineering.{{sfn|Lee|2000|p=163-166}}<ref>{{cite news |url=http://nla.gov.au/nla.news-article28621511 |title=The Sydney Morning Herald. |newspaper=[[The Sydney Morning Herald]] |location=New South Wales, Australia |volume=XLVIII |issue=7823 |date=3 July 1863 |page=4}}</ref>

The single track contributed to a fatal accident at [[Emu Plains]] in 1878 where eastbound and westbound goods trains collided.<ref name="Low" />

In 1890 signal boxes were built at both Lower and Upper Points of the Zig Zag, this was to replace the operation of pointsmen using hand levers.<ref name="NSWHD 1170821">{{Cite NSW HD|1170821|G024 : Lapstone Zig Zag|date=6 July 2009|access-date=2018-06-02}}</ref>

====The Glenbrook tunnel deviation====
{{main|Glenbrook Deviation (1892)|Glenbrook Tunnel (1913)}}
[[File:Arthur Streeton - Fire's on - Google Art Project.jpg|left|thumb|[[Arthur Streeton|Arthur Streeton's]] ''Fire's On'']]
Commissioner of Railways, E. M. Eddy, decided that the ZigZag should be replaced by the [[Glenbrook Deviation 1892|deviation]] including a [[Glenbrook Tunnel (1892)|tunnel]], both built around 1890. The Lapstone Zig Zag and Lucasville station were officially closed on 18 December 1892 and the rails were raised, after the completion of the Glenbrook Tunnel Deviation.<ref name="NSWHD 1170821"/> The Deviation soon experienced problems as it was built at the same too steep grade as the Zig Zag which caused the locomotives to slip in the tunnel, mostly due to water leaking onto the tunnel floor from nearby creek, and smoke also became a problem for uphill trains, as the tunnel was not designed to vent the smoke.<ref name="Low" />

The building of the tunnel is the subject of [[Arthur Streeton|Arthur Streeton's]] famous painting ''Fire's On''.<ref>{{cite web|url=http://www.artistsfootsteps.com/html/Streeton_fireson.htm |title=Artist's Footsteps |publisher=Artistsfootsteps.com |access-date=5 December 2011}}</ref>

=== Twentieth century ===
By 1910, the line as a whole was being duplicated (made into [[double track]]) and the "rathole" tunnel was replaced on a different deviation with a gentler alignment with 1 in 60 (1.67%) grades and the new [[Glenbrook Tunnel (1913)|Glenbrook Tunnel]] at Bluffs point on the Glenbrook Creek escarpment. From then on the lower section of the track, including the historic Knapsack Gully Viaduct, was converted into a road, the Great Western Highway, the main road up the Lapstone hill until the M4 motorway replaced it in 1993.<ref name="knpasack">{{cite web|author=Martin, David |url=http://infobluemountains.net.au/rail/lower/lapstone.htm |title=Lapstone Hill Railway Routes: Blue Mountains, Australia |work=Infobluemountains.net.au |date=28 February 2010 |access-date=5 December 2011}}</ref> The older tunnel was converted for mushroom growing but was also used by the [[RAAF]] for storage during [[World War II]].<ref name="tunnel">{{cite web|author=Martin, David |url=http://infobluemountains.net.au/rail/lower/glen-tunnel-old.htm |title=Glenbrook's old Railway Tunnel: Blue Mountains Railway Pages |work=Infobluemountains.net.au |date=9 December 1912 |access-date=5 December 2011}}</ref> During 1943 to 1946 the {{convert|660|m|ft|0|adj=mid|-long}} Glenbrook tunnel stored chemical weapons, mainly of bulk drums of [[Mustard gas|mustard]].<ref>{{cite web |author=Plunkett, Geoff |url=https://mustardgas.org/depots/ |title=Depots: Glenbrook Tunnel |work=Chemical Warfare in Australia |date=n.d. |access-date=14 May 2020 }}</ref> Today the Zig Zag, Knapsack Viaduct, The Old Glenbook Tunnel, and Lucasville station can all be accessed by walking tracks.

The Knapsack Viaduct is a sandstone [[arch bridge|arch]] [[viaduct]], designed by [[John Whitton]] and built by William Watkins. Its purpose was to carry the Main Western railway line across Knapsack Gully. It formed part of the Zig Zag, which climbed the eastern escarpment from Emu Plains to today's Glenbrook. Whitton also designed and built the [[Victoria Bridge (Penrith)|Victoria Bridge]] across the Nepean River at Penrith.

Construction of the Knapsack Gully Viaduct started in March 1863 by contractor W. Watkins, who also completed the stone piers of the Victoria Bridge at Penrith. Work was completed in 1865, with the bridge being constructed from local sandstone quarried in the neighbourhood around [[Lapstone, New South Wales|Lapstone]] and carried a single rail line.

The viaduct fell into disuse in 1913 after the completion of the Glenbrook Gorge Deviation. In 1926, after over a decade of disuse, the Knapsack Viaduct was taken over by the Main Roads Board. The board sought to improve the route of the Great Western Highway between [[Emu Plains, New South Wales|Emu Plains]] and [[Blaxland, New South Wales|Blaxland]], that at the time zig zagged up Mitchell's Pass which replaced Old Bathurst Road in 1832. The viaduct's carriageway was widened to allow for two car lanes, by trimming back the inside face of the stone parapets. The new road was opened by Governor Sir Dudley DeChair on 23 October 1926. The viaduct was again widened in 1939, with the construction of a reinforced concrete cantilevered deck, because of increased traffic use.

The final deviation of the [[Great Western Highway]], with the opening of the [[M4 (Sydney)#M4 Western Motorway|M4 Western Motorway]] in 1993, ended traffic flow across the Knapsack Viaduct. In 1995 the Viaduct was reopened to the public as part of the historic Lapstone Zig Zag walk.<ref name="NSWHD 4301012">{{Cite NSW HD|4301012|Knapsack Viaduct, Lapstone|access-date=2018-06-02}}</ref>

== Present day ==
The line of the old track and cuttings (including the long-abandoned platform of Lucasville station), and the old Knapsack Gully bridge is now a popular [[bushwalking]] track.<ref name="walks1">{{cite web|url=http://www.wildwalks.com/bushwalking-and-hiking-in-nsw/glenbrook-eastern-blue-mountains/lapstone-bridge-zigzig-walk.html |title=Wildwalks |location=AU-NS |publisher=Wildwalks |access-date=5 December 2011}}</ref> Often a cacophony of [[Bird vocalization|birdsong]] and insects can be heard where the gully is deep at the viaduct and it would tend to echo these sounds, especially that of the [[bell miner]]. Although the original tunnel is closed there is also a bush walk that will take you close to its entrance.<ref name="tunnel"/><ref name="walks2">{{cite web|url=http://www.wildwalks.com/bushwalking-and-hiking-in-nsw/glenbrook-eastern-blue-mountains/lapstone-train-tunnel-walk.html |title=Bushwalking on the Lapstone train tunnel walk hiking trail |location=AU-NS |publisher=Wildwalks.com |access-date=5 December 2011}}</ref>
