Sunbury line
The Sunbury line is a commuter railway line in the city of Melbourne, Victoria, Australia. Operated by Metro Trains Melbourne, it is the city's fifth longest metropolitan railway line at. The line runs from Town Hall station in central Melbourne to Sunbury station in the city's north-west, serving 16 stations via Parkville, Sunshine, St Albans, and Watergardens. The line operates for approximately 19 hours a day with 24 hour service available on Friday and Saturday nights. During peak hour, headways of up to 5 minutes are operated with services every 10–20 minutes during off-peak hours. Trains on the Sunbury line run with a seven-car formation operated by High Capacity Metro Trains.
The Victorian Railways began services in February 1859 on the line originally built to serve the town of Bendigo by the Melbourne, Mount Alexander and Murray River Railway Company. The line was progressively electrified over time, with electrification to St Albans in 1921, to Sydenham in 2002, and finally to Sunbury in 2012.
Since the 2000s, due to the heavily utilised infrastructure of the Sunbury line, improvements and upgrades have been made. Works have included replacing sleepers, upgrading signalling technology, two line extension projects, the construction of new stations, the removal of level crossings, the introduction of new rolling stock, and station accessibility upgrades.
On the 1st February 2026, the Sunbury Line was through routed with the Pakenham and Cranbourne lines, running through the Metro Tunnel via Town Hall station.
History
19th century
The Melbourne, Mount Alexander and Murray River Railway Company started to build a rail line to Bendigo before operations were taken over by the Department of Railways then the Victorian Railways. The line had been extended as far as Sunbury by February 1859. The line was duplicated between Footscray and Sunbury in early July 1859.20th century
of the line to St Albans was completed in October 1921, although electrification has already occurred to North Melbourne in May 1919 as part of the Essendon line electrification, and to Footscray in August 1920 as part of the Williamstown line electrification. Electrification shaved 10 minutes off the trip from St Albans to the city.North Melbourne to South Kensington was quadruplicated in 1924, and South Kensington to Footscray in November 1976. Automatic block signalling was provided between South Kensington and Footscray in August 1927, from Footscray to West Footscray in October 1927, North Melbourne to South Kensington in June 1928, Sunshine to Albion in July 1929, West Footscray to Sunshine in October 1929, and Albion to St Albans in February 1930, thus resulting in the entire electrified line being provided with this signalling.
21st century
Sydenham extension
On 27 January 2002, electrification of the St Albans line was extended along the regional V/Line tracks to Sydenham. The Sydenham electrification resulted in the closure of the original Sydenham station; a new station was built 600 metres south and named after the nearby Watergardens Town Centre. Additionally, another station was constructed in St Albans called Keilor Plains.Sunbury extension
Proposals for an extension of electrified metropolitan services to Sunbury have dated as far back as the 1969 Melbourne Transportation Plan. $270 million was set aside to complete electrification works as part of the 2008 Victorian Transport Plan, with works completed in 2012.There was some opposition to electrification. Concerns included a less comfortable journey, the removal of toilet facilities, the presence of a conductor, potential overcrowding, and congestion at level crossings due to the increase in the number of services. Bendigo line users also raised concern that electrification to Sunbury would slow down their trains to Melbourne. Ian Dobbs, then head of Public Transport Victoria acknowledged this issue, stating that "there's a slight slow-down of services on that particular corridor with this timetable, because we're putting more Metro services in the mix."
On 18 November 2012, the newly electrified line was renamed from the Sydenham line to the Sunbury line. Completion of the electrification increased the service frequency of Sunbury and Diggers Rest stations to 489 trains per week, an increase of 64% from the 298 trains per week when the service was operated by V/Line.
Sunbury Line Upgrade
In 2019, works began on the $2.1 billion Sunbury Line Upgrade project, delivered by the Rail Projects Victoria. The project upgraded the line to support the introduction of High Capacity Metro Train rolling stock and "take full advantage of the extra capacity created by the Metro Tunnel" which will open in 2025.Works delivered as part of the project include the installation of five new electrical substations: one in Delahey, one in Calder Park, rail yard two in St Albans, and one in Albion; ten more across the line were upgraded along with improvements to overhead wiring and signalling equipment to enable the use of "high capacity signalling" in the Metro Tunnel. Platforms were extended at Sunbury, Watergardens, Albion, Sunshine, Tottenham, West Footscray, Middle Footscray, and Footscray stations to support the longer HCMT rolling stock. Raised boarding pads were installed at Sunbury, Diggers Rest, Watergardens, Keilor Plains, Albion, Sunshine, and Footscray stations to improve wheelchair accessibility. Train stabling facilities at Sunbury, Calder Park, and Watergardens were upgraded, the level crossing at Gap Road, Sunbury was removed, and the tracks connecting the Sunbury line to the Metro Tunnel's portal at South Kensington station were laid.
Metro Tunnel
The 2012 Network Development Plan identified the need for a north–south tunnel connecting the Sunbury line to the Cranbourne and Pakenham lines. In 2017, the Metro Tunnel project began construction, consisting of twin tunnels bored underground between South Kensington and South Yarra stations, with five new stations along the route: Arden, Parkville, State Library, Town Hall, and Anzac. These works was completed in 2025, and went fully operational following the timetable change on 1 February 2026.Level crossing removals
The Level Crossing Removal Project has announced the removal of all 7 remaining level crossings on the Sunbury line, completed in stages from 2016 to 2025. In 2016, the level crossings at Furlong Road and Main Road, St Albans, were removed by lowering the rail line into a trench under the roads; St Albans and Ginifer stations were rebuilt. Another crossing was removed by elevating a section of the Melton Highway in Sydenham onto a bridge above the rail line in 2018. All remaining level crossings on the line were removed in 2025. The crossings at Old Calder Highway, Watsons Road, and Calder Park Drive were removed by building road bridges over the rail line, and the Holden Road crossing was closed to car traffic.Infill Stations
Currently, There is only one station proposed to be built on the Sunbury Line being at Calder Park. The station is planned to be located adjacent to Calder Park Drive.Network and operations

Operators
The Sunbury line has had a total of 7 operators since its opening in 1859. The majority of operations throughout its history have been government run: from its first service in 1859 until the 1999 privatisation of Melbourne's rail network, four different government operators have run the line. These operators, Victorian Railways, the Metropolitan Transit Authority, the Public Transport Corporation, and Bayside Trains have a combined operational length of 141 years.Bayside Trains was privatised in August 1999 and later rebranded M>Train. In 2002, M>Train was placed into receivership and the state government regained ownership of the line, with KPMG appointed as receivers to operate M>Train on behalf of the state government. Two years later, rival train operator Connex Melbourne took over the M>Train operations including the Sunbury line. Metro Trains Melbourne, the current private operator, then took over the operations in 2009. The private operators have had a combined operational period of years.
