Main North railway line, New South Wales
The Main North Line (also known as the Great Northern Railway) is a major railway in New South Wales, Australia. It runs through the Central Coast, Hunter and New England regions. The line was the original main line between Sydney and Brisbane, however this required a change of gauge at Wallangarra. The line is now closed north of Armidale, with the main route between Sydney and Brisbane now the North Coast line.
Description of route
The line starts as a branch off the Main Suburban line at Strathfield in Sydney. The line heads north as a double track electrified line through the northern suburbs of Sydney, crossing the Hawkesbury River Railway Bridge, before passing through the Central Coast.
At Fassifern, a former branch line to Toronto divided off in an eastwards direction until closed in 1990. The line continues north to Broadmeadow in the inner western suburbs of Newcastle. North of Broadmeadow is the junction with the Newcastle branch line. Electrification of the main line ends at Broadmeadow but continues along the Newcastle branch line.
The line then swings westwards as four tracks (two main line and two coal roads) through the outer suburbs of Newcastle to Maitland. Maitland is the junction of the North Coast line which continues to Brisbane. The line becomes double track immediately west of Maitland and heads through the Upper Hunter Valley through the townships of Branxton, Singleton and Muswellbrook where the double track ends.
Muswellbrook is the junction point for the cross country line to Sandy Hollow and Gulgong. The Main North continues northwards through the Ardglen Tunnel to Werris Creek, where the Mungindi Line branches off to Moree, and a cross country branch continues to Binnaway and ultimately Dubbo.
The line continues north, but sees limited traffic beyond Werris Creek. The line reaches the major New England towns of Tamworth and Armidale, the latter being the northernmost extent of service on the line. Until the mid-2000s freight traffic continued to the disused station at Dumaresq which is home to a now-also-disused agricultural fertilizer depot. There is now wire across the corridor at several points between Armidale and Dumaresq, after which the line is for all intents and purposes closed. A block is placed across the tracks at the 590 kilometre mark (a short distance on from Dumaresq), and north of Glen Innes the line, particularly its bridges, has fallen into disrepair. In December 1991 the line was severed when the Roads & Traffic Authority built a deviation of the New England Highway over the line at Bluff Rock south of Tenterfield. At Wallangarra, the line met Queensland Railways' Southern railway line.
The first section of the Main North line was built from the port of Newcastle to Victoria Street, Maitland in 1857 and extended to Singleton in 1863, Muswellbrook and Murrurundi in 1872, Werris Creek and West Tamworth in 1878, Armidale in 1883 and Wallangarra in 1888.
The Sydney to Newcastle section, Homebush to Waratah, had difficult topography to overcome, including crossing the Hawkesbury River, traversing the Mullet Creek bank and constructing the Woy Woy Tunnel. From the south, the line was opened between Homebush and Hornsby in 1886, then extended to Hawkesbury River in 1887. From the north, the line opened between Waratah and Gosford in 1887. Progress in the construction of the last section between Hawkesbury River and Gosford occurred when the Woy Woy Tunnel opened in 1887, then Mullet Creek to Gosford in 1888 and finally Hawkesbury River to Mullet Creek in 1889 when the original Hawkesbury River Railway Bridge was built.
In 1892, the line was duplicated from Strathfield to Hornsby, and electrified in 1926 as part of the Bradfield electrification scheme.
Several lines branch from the Main North Line, including:
- Newcastle Branch Line from Broadmeadow to Newcastle
- Richmond Vale railway line from Hexham to Weston (closed 1987)
- South Maitland Railway from Maitland to Pelton
- Merriwa line to Sandy Hollow and on to the Sandy Hollow to Gulgong line
- Mungindi line from Werris Creek to Narrabri and Moree
- Toronto line from Fassifern to Toronto (closed 1990 and converted to cycleway)
- Belmont line from Adamstown to Belmont (closed 1991 and converted to a cycleway called The Fernleigh Track)
- Morpeth Line from East Maitland to Morpeth (closed 1953)
- Barraba line from West Tamworth to Barraba (closed 1980s)
The line was serviced by the overnight Northern Mail until it ceased in November 1988. The Northern Tablelands Express provided a daylight service to Glen Innes, with some journeys extended to Tenterfield until truncated in October 1985 to Armidale and in February 1990 to Tamworth.
NSW TrainLink operates regional and intercity passenger services along the Main North line. A daily train operates from Sydney to Werris Creek before dividing, one operating along the Main North line to Armidale, the other section operating along the North-West line to Moree. Intercity passenger services operate between Sydney and Newcastle and between Newcastle, Maitland and Scone, with a branch to Dungog on the North Coast line. Sydney Trains operates suburban passenger services in the section between Strathfield and Berowra.
The section between Strathfield and Maitland forms part of the interstate line between Sydney and Brisbane and sees intermodal freight traffic carried between the two cities. The section of line in the Hunter Valley sees intensive coal train working, with the section between Broadmeadow and Maitland one of the busiest freight lines in Australia.
The line was hampered by the rugged terrain and a change of gauge at Wallangarra for traffic to Queensland. The line was superseded as the principal route to Brisbane by the completion of the North Coast Line in 1930. Despite being bypassed, the line remained busy for many years afterwards, with the line instead becoming the major freight link to the wheat and wool regions of northern and north-west New South Wales.
In 1988 the line between Tenterfield and Wallangarra was closed. The last train to operate north of Tenterfield was an Australian Railway Historical Society charter on 15 January 1988 hauled by diesel locomotive 4487. The last train to operate north of Glen Innes was hauled by steam locomotive 3001 on 22 October 1989 after which the line was formally closed.
Following the Northern Tablelands Express being truncated in February 1990, the line north of Tamworth saw little use until the Xplorer service was introduced to Armidale in October 1993. The line to Glen Innes was still open in July 1992 when diesel locomotive 4499 operated a crew training service.
There have been attempts to revive freight or tourist traffic to as far as Glen Innes, although these plans have not yet succeeded.
A section of the line between Waratah and Maitland is quadruple track, with one pair being used exclusively for coal trains within the Hunter Valley coal trains and the other pair being used by passenger trains and general freight. The coal tracks from Port Waratah join the line on the eastern side of the other tracks at Scholey Street Junction and pass underneath the other tracks at Hanbury Dive just west of Maud Street, continuing to Maitland on the western side of the other tracks.
The Sandgate Flyover was constructed in 2006 to allow the two passenger/freight tracks to rise and pass over the coal tracks that branch off to Kooragang Island in order to eliminate a capacity restriction caused by the long coal trains crossing the other tracks at grade. Because of the location of the overpass relative to the branch to Kooragang Island, a short section of the line has 6 parallel tracks. The bridge carrying Sandgate Road over the lines had to modified to allow for the additional lines. Sandgate station is flanked by a pair of coal tracks on each side.
In 2011 the Northern Sydney Freight Corridor project commenced to improve access for freight trains. This has seen the completion of a loop at Hexham in June 2012, with an underpass and loop being constructed between North Strathfield and Rhodes, a third track between Epping and Pennant Hills and two loops between Gosford and Narara. These are due for completion in 2015/16.
