Gawler railway line

Renewal

In 2008, the State Government announced a plan to rebuild the Gawler line in preparation for the line to be electrified with the Federal Government also to provide funding.^[3] This work saw the track removed, and the track bed, sleepers and track renewed. Dual gauge sleepers were laid to allow for the line to be converted to standard gauge at a future date. The line was closed between North Adelaide and Mawson Interchange for four months from June 2010 for this work to be performed, and between Mawson Interchange and Gawler Central station for seven months from September 2011.^[4][5][6]

On 6 February 2011, a new Adelaide Metro railcar depot opened to the east of Dry Creek station to replace the facility behind the new Royal Adelaide Hospital site and Adelaide station.^[7] The depot is the major maintenance and re-fuelling facility for the 2000 and 3000 class diesel fleets, with capacity to store 70 railcars with over 11 kilometres of track. The depot has been designed to allow future conversion to support electric rollingstock.

The last freight service on the line was the Penrice Stone Train which operated to Penrice until June 2014.^[8] Since 2015 the line has been served by Adelaide Metro services using 3000 class railcars operating from Adelaide station to Gawler Central station;^[9] the 2000 class railcars were retired in August 2015.^[10]

Following the withdrawal of the Federal Government funding, the electrification was postponed in October 2013.^[11] In 2017, the Gawler line between Adelaide and Mawson Lakes was closed along with the Outer Harbor and Grange lines during April, June, July, and August to work on the Torrens Rail Junction Project in Bowden.^{[12][13][14][15]} In mid-September 2017 it was announced that from 1 to 15 October the Gawler and Outer Harbor lines line would be closed for major works to build a rail underpass at Park Terrace, Bowden.^[16] Delays in works pushed the opening from December 2017 to January 2018^[17]

Following a decade of on-again, off-again talks,^[18] electrification of the Gawler line was announced in 2018. The announcement only promised Stage 1 electrification as far as Salisbury with works to commence in 2018.^[19] A $220 million grant from the Federal Government also allowed for Stage 2 electrification for the remainder of the line to proceed. Works are expected to commence in 2018-19 to be completed by the end of 2020.^[20]

Commuter

All suburban rail passenger services are operated by Adelaide Metro. On 28 April 2008, new timetables were introduced on the Gawler line in an effort to boost efficiency. Shorter secondary services that terminated at Dry Creek and Salisbury were withdrawn, new limited express services were introduced, and a new Hi-Frequency station policy adopted.^[9] Nearly all services either start or terminate their journey at Gawler or Gawler Central stations, apart from a morning peak express service that commences its journey at Salisbury.^[9]

Under this policy, the Hi-Frequency stations (Islington, Mawson Interchange, Parafield, Salisbury, Elizabeth, Smithfield, Tambelin and Gawler) have services every 15 minutes, while all other stations have a 30-minute service. This is in addition to several peak hour express services that stop only at selected Hi-Frequency stations.^[9]

Weekend services operate with 30 minute frequency, and every second train runs express between Adelaide and Dry Creek using 3000 class railcars. Evening/Night services are hourly and stop at all stations with the exception of North Adelaide.^[9] Until April 2008, most services along the line were operated by 3000 class railcars. However, with the introduction of the new timetable, 2000 class railcars became more frequent, especially during peak hour.

Freight

Freight is still a major factor along this transport corridor, with the Australian Rail Track Corporation's standard gauge Adelaide to Port Augusta line running parallel to the broad gauge track between Adelaide and Salisbury. Since 1984, this line has been standard gauge and had no interface with the suburban lines. Aurizon, Genesee & Wyoming Australia, Pacific National, SCT Logistics, and Great Southern Rail operate services via the line, with the latter operating The Ghan and Indian Pacific passenger trains along this section. Until 2007, grain trains operated from Roseworthy to Port Adelaide. The last freight service on the Gawler line was the Penrice Stone Train which operated to Penrice until it ceased operating in June 2014.^[8]
