Once you've determined the coords, this will lead you to WP1 Here you will find a sign with two distances on it, A and B. Use these numbers to determine the location of GZ.
For South coordinates add (170 x A) to WP1 coords.
For East coordinates add (287.5 x B) to WP1 coords.

Some location info:
In 1884 Amos&Co. constructed the third and last standard gauge Zig Zag railway in NSW. This Zig Zag overcame the significant climb to the main line near Thronleigh Station from the quarry 35m below. The Zig Zag downline left north of Thornleigh station and crossed The Esplanade in a south westerly direction to the northern end of Werona St, Pennant Hills. The line then followed a lower contour to Janet Avenue. From here the line switched back in a westerly direction along the creek to the quarry below Oakleigh Park.
The hard sandstone ballast was crushed near the quarry face, loaded into railway trucks and transported for use on the Homebush (Sydney) to Waratah (Newcastle) Railway Line. The ballast was carried in trucks pulled by a Kitson 0-6-0 steam engine named Westward Ho. The quarry lay idle from 1886 to 1891 when it was re-opened by the contractors for the North Shore Line. After 1906 the quarry was used by Hornsby Shire Council for road metal until about 1920. In 1976 the Pennant Hills Apex Club constructed an interpretation circle in the quarry.
The worker’s camp associated with the railway quarry was called Hall’s Camp after Thomas Hall the Chief Accountant for the NSW railways. It was described in 1888 as a place of primitive and hastily erected canvas and bark dwellings with pretentious corrugated iron buildings such as the Boarding House and General Store. Houses in Morgan St and Dale Close now cover the site.
