The Zig Zag Railway appeals to children and adults alike, especially those who once rode behind steam locomotives on the way to school or on holidays. It is a magical step back in time, filled with sights, sounds and smells of a bygone era. Every trip from Clarence Station winds its way through the remarkable Blue Mountains’ scenery, offering glimpses of grand sandstone viaducts, accompanied by the chuffing steam locomotive. It is a chance to appreciate the difficult terrain that confronted the builders and marvel at how they brought the railway down into the Lithgow Valley and on westward.
