Lithgow

A railway zig zag is a series of reversing ramps used to avoid very steep grades. John Whitton, Engineer in Chief NSW Government Railways 1856-90, chose this as the economical method for the descent from Clarence to Lithgow. Built during 1866-69 by contractor Patrick Higgins, it involved massive rock excavations, a tunnel and three stone arch viaducts. During its 41 years of operation it accelerated the development of western New South Wales and achieved world renown as a major engineering work.
