Denniston Incline (1879)

Hell on earth halfway up ‘The Hill’

The boosters called it the ‘Eighth Wonder of the World’. The poor sods forced to slog away in the mines up ‘The Hill’ sang a different tune:

‘Damn Denniston
Damn the track
Damn the way both there and back
Damn the wind and damn the weather
God damn Denniston altogether.’

They had reason to complain, for Denniston was a miserable hole, a gimcrack clutter of corrugated iron and weatherboard buildings clinging precariously to a bleak plateau. Thick fog could hang around for weeks on end, as could steady drizzle. In between times it bucketed down, yet little grew here apart from rust, emphysema and the politics of dissent. The soil was so thin they had to send bodies down the incline for burial elsewhere.

Denniston (named after R.B. Denniston, the company’s surveyor and colliery manager) was the bleak jewel in the Westport Coal Company’s crown. It was also the country's most productive coalfield. From its offices in Water Street, Dunedin, Westport Coal collaborated with the Union Steam Ship Company to dominate the colony’s fuel and transport industries. Between 1879 and 1967, 13 million tonnes of coal was sent down the incline to Union Steam Ship Company colliers at nearby Westport.

It was a technical triumph. The incline plunged precipitously, 548 m in a distance of just 1670 m, with some grades as steep as 1 in 1.25 (80%). Two water-operated brakes, Upper Brake and Middle Brake, slowed the progress of the counter-balancing wagons (i.e., descending full wagons pulled up empty ones) down the two inclines to the railhead at Conns Creek.

The regenerating bush is reclaiming the upper (number one) incline, but the lower (number two) incline can be admired from a nearby walking track. You can see rusting wagons, wire by the kilometre, stretches of track, and an impressive drive tower at the top of the incline. A few people still inhabit the township, where the Friends of The Hill have restored the old schoolhouse. Tracks lead to other former mines and features. Keep to them and watch out for old shafts.

On the ground

The Friends of The Hill run a museum in the township. Elsewhere, there are plenty of signs, markers and other objects of interest.

I have been up to Denniston 3 times. Walked all over the place. Was lucky enough to do the mine tour before it was closed down. Will defo visit again one day.

My wife, Elizabeth, and I heard about the Bush walking on Denniston Plateau from good friends who owned the Top 10 Holiday Park in Westport.
We drove our car to the top and walked the tracks. It was a vast area of abandoned coal mine infrastructure from the 1800’s and the years until closure in the mid 1960’s. Old roadways, footpaths and abandoned Railway Lines, many old dwellings are there to show the huge workplace it once was.
We made a point of going to wander around Denniston Incline Plateau every time we went to New Zealand. 12 times, always included a slow hire car circuit of South Island, with a long stay in Cromwell as a base. Coalbrook dale mine and Denniston Incline gave us a perfect place to ramble.
Nature is reclaiming the whole Plateau.
