Glenbrook Historic Railway Walk

The Lapstone Monocline is a geological feature at the eastern edge of the 500 meter uplift that commenced 15-22 million years ago to create the Blue Mountains. This uplift proceeded very slowly, such that the then existing streams like the Nepean River, Glenbrook Creek , the Grose and Colo Rivers were able to maintain their beds, flowing to the east, because the rate of erosion kept pace with the rate of uplift.

On the eastern side, facing Emu Plains and Richmond the 190-250 million year old Triassic strata has been tilted upwards- the Lapstone Monocline- to create a formidable barrier to road and rail construction.

There were three phases of railway construction to scale the monocline:-

Stage 1 :- The Lapstone Zig-zag railway built 1863-65 as an alternative to the then proposed and unaffordable 3 km tunnel along the Grose Valley.

The spectacular Knapsack Gully Viaduct and Lucasville Station (built because John Lucas, Minister for Mines, had a holiday house there!!) are a part of the zig-zag construction.

Several problems soon became obvious:-

  • The length of trains was limited by the length of the switchbacks
  • Because of the single track, trains had to wait their turn at sidings- the closest was at Wasco Siding, now Glenbrook.
  • There was a serious collision at Emu Plains in 1878.

Stage 2:- The First Deviation 1891-92. This involved the construction of a 660 meter long single track tunnel at a steep 1:33 gradient to allow trains to move directly from the Knapsack Viaduct to Glenbrook Station (the original site next to the Gt. Western Highway).

New problems soon appeared:-

  • The gradient of the tunnel was too steep and steam engines would slip on the tracks and trains frequently had to reverse out to get a better run up.
  • Ventilation was a serious problem in the narrow tunnel- smoke from wood, then coal fired engines ( carbon monoxide) tended to cause asphyxiation
  • Another serious accident in 1908

This tunnel portal is the subject of Arthur Streeton’s famous painting ‘Fire’s On’ that can be viewed at the AG of NSW

Stage 3:- The Second Deviation built in 1910- 12. The main feature is the currently used double track tunnel at a grade of 1:66 along Glenbrook Gorge and the subsequent release of the Knapsack Viaduct to become a road.

To facilitate construction of the new tunnel, a tramway was built on contour from the present Lucasville Road to the edge of Glenbrook Gorge. The route if the tramway is still obvious.
