History

Historical notes: By May 1869 the northern line had reached Muswellbrook, linking Sydney to the Upper Hunter Valley, with the Singleton to Muswellbrook section of the line opened on 19 May 1869. The Muswellbrook to Aberdeen section was opened in October 1870 and by April 1871 the railway had reached Scone. The next section (to Murrurundi) was difficult to build, with steep grades and heavy earthworks required, but by 5 April 1872 the line had opened to Murrurundi, completing the first stage of the development of the northern line between Sydney and Murrurundi (Cottee, 2004; SRA, 1993).

Due to budget constraints, the next stage included sharper curves, steeper gradients and a shorter tunnel through the Liverpool Ranges than originally intended. In 1872 the NSW Legislative Assembly decided that future railway extensions were to be built using standard-gauge tracks, and by 1873 the extension of the northern line beyond Murrurundi was permanently staked and designed for a standard-gauge track with sharper curves and steeper grades than originally proposed, and with narrower cuttings (Cottee, 2004).

Tenders for the next stage of the northern line were called in January 1874 and in March 1874 the winning tender was accepted for construction of the line as far as Tamworth. Worked commenced in 1874 but was slow, with the original completion date of March 1876 not met. While the line was not even close to completion, by August 1876 the first locomotive went through what is now known as the Ardglen Tunnel. By December 1876 the 488-metre long tunnel was officially completed (some records show it as completed on 13 August 1877) but it wasn’t until October 1878 that the northern line reached Tamworth and January 1888 when the line reached the Queensland border at Wallangarra (Cottee, 2004; SRA, 1993).

The Ardglen tunnel remains in use as an essential part of the railway infrastructure on the Northern Line.
