Zig Zag Railway is a heritage railway at Lithgow
in New South Wales
on the site of the famous Great or Lithgow Zig Zag which operated between 1869 and 1910. The Zig Zag Railway is closed for an indefinite period following accreditation issues with the New South Wales Government. The last passenger train ran on 17 June 2012.
As built, the line formed part of the Main West line from Sydney
across the Blue Mountains
and served to lower the line from its summit into the Lithgow valley on the western flank of the mountains. The Zig Zag railway ran steam and diesel hauled trains over the Zig Zag for tourists.
The railroad was unique in NSW as being the only heritage operator to run everyday except Christmas Day. On Mondays, Tuesdays, Thursdays, Fridays, and Sundays railmotors were operated. Every Wednesday, Saturday, and Sunday a steam loco with train would operate. Sunday had a two train timetable. Special events included a Day Out with Thomas and a Wizards express event held a couple of times per year. During most of the NSW school holidays steam services ran every day.
