Zig zags suffer from a number of limitations: The length of trains is limited to what will fit on the shortest stub track in the zig zag. For this reason, the Lithgow Zig Zag's stubs were extended at great expense in 1908. [5] Even then, delays were such that the zig zag had eventually to be bypassed by a new route, opened two years later.
The deviation comprises ten tunnels of varying length from 70 to 825 metres (77 to 902 yd) that carry the double-track 1,435 mm (4 ft 8 + 1 ⁄ 2 in) standard gauge Main Western line between Newnes Junction and Lithgow Zig Zag stations. The work also included the excavation of the deepest cutting of 61 metres (200 ft) on the New South Wales ...
It had no goods service, but a zig zag track branched off just outside the station from a point on the main line towards Saltburn, [3] serving the Loftus Mines in the valley below, where ironstone was mined. [4] This closed in 1958. [3]
The line originally ascended the eastern and descended the western sides of the Blue Mountains via a series of zig-zag track sections. The eastern zig zag was by passed by a tunnel in 1892 and the western zig zag (currently a tourist railway ) was bypassed in 1910 with the Ten Tunnels Deviation .
In mathematics, a chaotic map is a map (an evolution function) that exhibits some sort of chaotic behavior. Maps may be parameterized by a discrete-time or a continuous-time parameter. Discrete maps usually take the form of iterated functions. Chaotic maps often occur in the study of dynamical systems.
