The Williamstown line is a commuter railway line in the city of Melbourne, Victoria, Australia. Operated by Metro Trains Melbourne, it is the city's third shortest metropolitan railway line at .
The line runs from Flinders Street station in central Melbourne to Williamstown station in the inner west, serving 12 stations via Footscray, Yarraville, and Newport. The line operates for approximately 19 hours a day (from approximately 5:00 am to around 12:00 am) with 24-hour service available on Friday and Saturday nights. For most of the day, the line operates with headways of 20 minutes, ensuring frequent service for commuters. Trains on the Williamstown Line run with two three-car formations of Comeng and Siemens Nexas trainsets.
Together with the Southern Cross to Sunbury portion of the Deniliquin railway line, it is the first and oldest government-built line in Victoria, having opened on 13 January 1859. The line was built to serve the port at Williamstown, giving it economic importance to the then-colony as it established itself as an important international passenger port. The line has played an important part in the development of Victoria's railways, with the first workshops opening along the line in the 1800s.
Since the 2010s, due to the heavily utilised infrastructure of the Williamstown line, improvements and upgrades have been made. Works have included replacing sleepers, upgrading signalling technology, the removal of level crossings, the introduction of new rolling stock, and station accessibility upgrades.
Until February 2026, weekday services on the Williamstown line were through routed with the Frankston line and the line was coloured green. On 1 February 2026, Frankston line trains returned to the City Loop. As a result, the weekday services terminated at Flinders Street Station as a temporary arrangement, with no services continuing beyond Flinders Street. The colour of the line was also changed to pink, the same colour as the Sandringham line. Since 23 August 2026, the weekday Williamstown line services are through routed with the Sandringham line.
History
19th century Construction of the line was started by the Melbourne, Mount Alexander, and Murray River Railway Company (MMA&MRR) with the construction of Batman Hill (now Southern Cross) station in 1853. Interestingly, the station did not see a train for another 6 years till services began in 1857. In response to 12 months of inaction by the MMA&MRR and pressure from the government and financial backers, the company organised a gala event at Williamstown on 12 June 1854.
Recognising the challenges faced by private companies and the pressing need for railway development, the government took action to address the situation. On 19 March 1856, despite only small sections being completed, the government intervened and acquired the line, assuming responsibility for its construction and further development.
In 1858, the Williamstown Workshops opened for the assembly of engines and carriages imported from England. Other buildings were soon added, with a total of seven locomotives built. During the late 1880s when railway management described the workshops as inadequate, moves were made to construct new workshops at Newport. By 1889 the new shops were open and Williamstown was closed.
Although it is now operated as a branch from the main Werribee/Geelong line at Newport, the line was originally built from the city with the Geelong line being the branch. The line officially opened in January 1859, but the section between the Newport Workshops and Williamstown Pier was in use by Geelong-line trains from October 1857 as it provided a connection to the ferry services departing from the pier. From Williamstown Pier, passengers could connect to a ferry across Hobsons Bay to Port Melbourne.
20th century In August 1920, the line was fully electrified from North Melbourne to the Williamstown Pier. Later in 1927, the section from South Kensington to Footscray received three-position signalling with further extensions of the three position signalling occurring in 1929 and 1997.
Due to the proximity to the nearby wharf facilities, the Williamstown line provided a vital connection between Melbourne and the freight and passenger facilities at the port provided. The railway was built to serve the Government port at Williamstown, giving it great economic importance to the Colony of Victoria and establishing its role as an international passenger port.
The Newport Workshops in Victoria have played a significant role in the railway system, highlighting their importance through various expansion initiatives. Notable expansions took place from 1905 to 1915 and again from 1925 to 1930. At the peak of operation it was one of Victoria's largest and best-equipped engineering establishments, with up to 5,000 employees on site. The workshops had their own cricket grounds, and the game of Trugo is said to have been invented by workers on their lunch hour in the 1920s. In the late 1980s, the original segments of the workshops were removed from everyday use with modern workshops built along the eastern side of the site, which remains in use today.
The only section of the line to have closed was the Williamstown to Williamstown Pier section which closed in March 1987.
21st century In January 2021, a major timetable rewrite resulted in increased frequencies and weekend daytime shuttle services being extended from Newport to Flinders Street. Peak hour weekday services now stop at South Kensington, which simplifies stopping patterns on the Werribee and Sunbury lines.
When the Metro Tunnel was under construction, there was a plan by the state government to reorganise the Melbourne rail network. The plan included the return of the Frankston line to the City Loop, with dedicated use of the Caulfield group tunnel track. This would mean Frankston line trains would no longer through-run with Werribee and Williamstown line trains, and would again stop at City Loop stations Flagstaff, Melbourne Central and Parliament. As part of the reconfiguration, the Werribee and Williamstown lines would instead begin through-running services to Sandringham for the first time. The Metro Tunnel eventually fully opened in February 2026, and through-running services between the Williamstown and Sandringham lines began on 23 August 2026.
Future Level crossing removals
The Level Crossing Removal Project has announced the removal of 3 level crossings on the Williamstown line, to be completed in stages from 2021 to 2030. In 2021, one level crossing was removed at Ferguson Street in Williamstown. The crossing was removed by lowering the rail line onto a rail trench under the road, with the adjacent North Williamstown station also being lowered. A final two crossings will be removed along the line by 2030. The crossing at Hudsons Road in Spotswood will be removed by elevating the rail line above the road with Spotswood station also being rebuilt as part of the project. The crossing at Anderson Street, Yarraville, will be closed off as part of other level crossing removal works. At the end of these works, the Williamstown line will have 1 remaining crossing at Giffard St in Williamstown that is not scheduled for removal.
Network and operations
Services Services on the Williamstown line operate from approximately 5:00 am to around 12:00 am daily. In general, during peak hours, train frequency is 10 minutes while services during non-peak hours drop to 20 minutes throughout the entire route. In combination with the Werribee line, frequencies are boosted between Newport and Flinders Street.
Services on the line do not run through the City Loop. Instead, most daytime services on weekdays continue onto the Sandringham line, while daytime services on weekends (between midday and evening) and occasional weekday peak hour services terminate at Flinders Street. At other periods with low patronage, shuttle services operate between Newport and Williamstown operate at nighttime (daily), weekend mornings, and as part of the Night Network. Night Network operates on Friday and Saturday late nights, with services running 24 hours a day with 60-minute frequencies available outside of normal operating hours.
Train services on the Williamstown line are also subjected to maintenance and renewal works, usually on selected Fridays and Saturdays. Shuttle bus services are provided throughout the duration of works for affected commuters.

Operators
The Williamstown line has had a total of 8 operators since its opening in 1859. The first section of the line from near Newport to Williamstown Pier was originally opened by the government in 1857 and used by the Geelong and Melbourne Railway Company (G&MR) until the remainder of the government line to Spencer Street (now Southern Cross) opened 2 years later in 1859. This was operated by the government under the newly formed Victorian Railways (VR) using the full length from Williamstown Pier to Spencer Street (G&MR then used the VR line from Newport to Spencer Street). Many operators throughout its history have been government run. From its government acquisition in 1856 until the 1999 privatisation of Melbourne's rail network, four different government operators have run the line."Melbourne's Rail Network to be Split" Railway Digest November 1997 page 12 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.National Express walks out of Australian rail service The Daily Telegraph (London) 17 December 2002Receivers take over train, tram group The Age 24 December 2002Victorian passenger services get new managers Rail Express 28 January 2003 Two years later, rival train operator Connex Melbourne took over the M>Train operations including the Williamstown line. Metro Trains Melbourne, the current private operator, then took over the operations in 2009.
