The Driving Creek Railway of today is the second railway Barry has built, the first being located just up the road at 90 Driving Creek Road, Coromandel. It was 250 metres long with a 10½-inch (266mm) track gauge being smaller than the present day railway at 380 Driving Creek Road. The railway infrastructure was removed to the present day railway, all that remains of the original railway on the property today is a 20-metre tunnel.
The present day Driving Creek Railway climbs 2.7km from the Base Station at 55 metres above sea level to EyeFull Tower at 167 metres above sea level, a total climb of 115 metres. With an average gradient of 1-in-24.1 (1 vertical metre for every 24.1 metre of length) the Driving Creek Railway is New Zealand’s steepest railway.
The gradient varies considerably, with the steepest section being 1-in-14.
The track gauge is 15 inches (381mm), a gauge chosen to allow for tight track curves and to limit the amount of earthworks required on site.
