Woy Woy Tunnel

Woy Woy Tunnel is a railway passage stretching 1.69 kilometers through solid rock with brick entrance portals and a horseshoe-shaped cross-section along the Main Northern railway line. The two openings at either end frame the dark passage where trains navigate through the challenging terrain between Sydney and Newcastle.

The tunnel was built between 1884 and 1888, making it the longest railway tunnel in Australia upon completion. This project marked a major advance in Australian railway infrastructure and significantly improved connections between Sydney and Newcastle.

The tunnel represents the determination of 300 workers who utilized dynamite and rock drills to create this essential transportation connection between Sydney and Newcastle.

The best time to view this site is during regular train service hours when you can observe trains passing through the tunnel. Access may be limited, so it is wise to check beforehand for any restrictions or guided tour options available.

Archaeological remains of worker camps near the Mullet Creek portal reveal evidence of how people lived during the tunnel's construction. These findings give insight into the daily challenges faced by over 300 workers who participated in this demanding project.
