The Werribee railway line is a commuter rail passenger train service in Melbourne, Australia, operating between Werribee in the western suburbs to Flinders Street in the central business district. The line traverses the flat plains of Melbourne's western suburbs, and after leaving Footscray, has no significant earthworks. The area around the outer end of the line has seen significant residential growth in recent years, resulting in strong patronage growth. It is part of the Melbourne metropolitan rail network operated by Metro Trains. Infrastructure The Werribee line consists of multiple tracks, shared with other lines, from the City Loop until South Kensington, after which it becomes double track. From Newport South Junction, which is about after Newport, the two tracks are signalled for bi-directional operation, although it is very rare for trains to use the possibility of right-hand running. About one and a half kilometres from Newport South, the Altona branch diverges at Altona Junction. It is a single-track branch, apart from a passing loop at Westona, and rejoins the main line at Laverton. Automatic block signalling applies to Newport South, situated at the Champion Road level crossing, and from Newport South through to Werribee (and then all the way to Geelong), the line is controlled by automatic and track control safeworking, both via Westona and the main line. Terminating facilities for trains are provided at Newport and Laverton. Newport is also the location of the Newport Workshops, formerly the main workshops of the Victorian Railways. Stabling facilities for suburban trains are provided at Newport Workshops, and trains are also stabled overnight in the platform at Werribee. Next generation passenger information display screens (PIDS) have been installed at most stations along the Werribee Line, apart from South Kensington, Aircraft and Spotswood.
