Glowworm Tunnels

Me and Mandy

Built in the early 1900’s to cart goods and supplies (and people as an afterthought) into and out of the new shale mine in the Wolgan valley the Newnes rail line was a marvell. 31miles (~50km) long, including 2 curvng tunnels carved through the sandstone where the line descended through the clifflines at Penrose gully, it took just 18months from survey through wild terrain to having trains run.

The trains themselves were special Shay locomotives that had a unique vertical piston and gearing arrangement that was able to deliver steady power to all wheels via drive shafts thus they were able to negotiate the steep grades and tight bends required to get out of the valley.

The line was always a bit of a problem child though. Not only were mining conditions in the Wolgan far harsher then expected (the seam was easier to mine from the Capertee) but maintenance on the track was expensive. The little culvet bidges used to span the “Dry gullies” proved completely in adiquate for the “gully rakers” and flash floods produced by summer storms. By 1934 the line was closed. Much of the remaining track and infrastructure were pulled up and shipped over seas for the WW2 war efforts in Egypt and Turkey.

The line was left to deteriorate but the second tunnel, with water now running through it from tunnel creek became the home of glowworms which exist naturally in the canyons and caves throughout the plateau and are a larvae stage of a gnat.

Being able to see glowworms in the day in an easily accessable spot soon became a draw card tourists and much of the line above tunnel became an access road.

 

Anyhoo. I’ve visited the tunnels many times and I always enjoy it. Dad took us there as kids, I took my kids when they were little and we’ve done it many times with friends and family. Now days though my visits are usually part of either a longer mountian bike ride or as a side trip from near by canyons. Each time I go I try and snap a photo of the ferns looking out of the tunnel and invariably it the photo ends up either with the ferns too washed out in the bright sun or the tunnel too dark or both.

Then I had a bright idea and contrived a plan to slip up at night to see what I could capture.

No matter how many times I do it driving through the first tunnel on the way to the car park is always an awesome experience
