The Williamstown railway line is a commuter rail passenger train service in Melbourne, Australia, operating between Williamstown in the western suburbs to Flinders Street in the central business district. It runs across flat coastal land and therefore has no significant earthworks. From the junction at Newport to the next station of North Williamstown, it runs beside the Newport Workshops, and from there through mainly old residential areas. The line used to continue a short distance to Williamstown Pier, around which there is heavy industrial areas including shipbuilding. Infrastructure The Williamstown Line shares tracks with the Werribee line between Flinders Street and Newport. The line is double track throughout, except for Williamstown station, and provided with automatic block signalling. There are no intermediate terminating facilities. Stabling facilities are provided within the grounds of the Newport workshops. Services Trains on the Williamstown line stop all stations. In general, trains run every 20 minutes during regular hours. As the Werribee and Williamstown lines merge at Newport towards Flinders Street, frequency is doubled. Regular 10-minute intervals are formed of Williamstown and Laverton (via Altona) services. Shuttle services between Newport and Williamstown occur in the evenings, weekend mornings, and as part of the Night Network. Newport is where passengers change into trains to or from the city. These shuttles are operated as 3 car train-sets. Inbound shuttles terminate on platform 1 at Newport and are stored in a siding on the city side of the station. The siding allow trains to reverse and form outbound Williamstown shuttle services departing from platform 2.

Legend – Stopping Patterns ● – All trains stop History and future 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 vicinity of the Newport workshops and Williamstown Pier was in use by Geelong-line trains from October 1857 (see the history of the Werribee line for more information). The line was electrified in August 1920, but little further change to the infrastructure took place until the section from Williamstown to Williamstown Pier closed in March
