Ulan Line Tunnels

Site visit by potential contractors. Tunnel three (Bylong) Up end. The 375-107 is the distance from Sydney in Kms. The tunnel is single track and is 1.975Km long. August 1993. HWW my viewers for 12/06/24. The earth works, 5 tunnels and numerous bridges were constructed in the 1930s but track wasn't laid until the 1980s in the Sandy Hollow to Gulgong section and is never likely to be laid in the Gulgong to Mary Vale section. The tunnel closest to Sandy Hollow was used as a road between its construction and the track being laid.

Site visit by potential contractors. Tunnel four Up end. August 1993.

My final visit to this site at the western end of the Bylong No. 3 tunnel on the Ulan line. Operations looked after it from then. See PiP for overhead view of hut. The site was powered by solar and a diesel generator. Solar was limited by the deep, steep sided valley. February 1998.

The Bylong No. 3 Tunnel is 1.95 Km long and straight. February 1998.

Initial site visit to belt a Train Radio hut location peg into the ground across the track from the Patrol (see note). October 1993.
