History

Historical notes: The original line of railway which was opened in 1867 scaled the escarpment above Emu Plains by the Lapstone Zig Zag. At the top of the Zig Zag the railway followed the route now occupied by the Great Western Highway through Glenbrook as far as Blaxland. Because of the delays caused by the Lapstone Zig Zag and the increase in rail traffic, it was decided in 1891 that a tunnel should be built bypassing the Zig Zag. The tunnel and its new approaches were designed to form an elegant S-shape, starting at the Bottom Points of the Zig Zag and ending at old Glenbrook station (now demolished, on the present Great Western Highway).

The building of the tunnel in 1891-2 was contracted to George Proudfoot, whose labourers and their families were established in two substantial camps at either end of the works, one at Glenbrook, the other at Lapstone. Because of Sir Arthur Streeton’s great painting ‘Fire’s On!’, the building of the tunnel and the fatal blasting accident which killed Thomas Lawless have become part of Australian mythology as well as railway history.

The new tunnel opened to traffic on 18 December 1892, but it was never a success, because of the steep incline and the suffocating atmosphere particularly in the west-bound trains. The problem was finally addressed after the Lithgow Zig Zag deviation was completed in 1910 and the railway gangs were moved to Glenbrook. Really major works were involved in bypassing Glenbrook Tunnel: a new viaduct (G 025) was built over Knapsack Gully to the east; and the new line then ran through virgin country south of the old alignment as far as the present Lapstone station and then turned west through a short tunnel under The Bluff and finally north to the present Glenbrook station.

Initially it was planned to continue using the 1892 Glenbrook Tunnel for up trains and when the new deviation opened on 11 May 1913 the tunnel was still used for east-bound trains. But the new line had been duplicated and the up line was activated in September. Glenbrook Tunnel was last used for trains on 25 September 1913 and old Glenbrook station was closed.

The lines in the tunnel were raised and it quietly decayed until, like some other disused railway tunnels, it was reopened as a mushroom farm. Today the entire 650 metres underground are occupied by mushrooms, grown by Mushroom Biotech under a lease granted by the State Rail Authority.
