Infrastructure
The line is quadrupled to South Kensington railway station, then is double track for the rest of the line, although from South Kensington to Footscray, it runs alongside the Werribee line, effectively extending the quadruple track to there.
The line is also paralleled by a double track goods line and the interstate standard gauge line, the latter being dual gauge with the goods line to West Footscray. The goods line joins the Sunbury line at Sunshine, whilst the standard gauge line to Sydney continues to run alongside the suburban line to Albion, where it and a goods line head off in a north-easterly direction.
The line is controlled by automatic block signalling throughout. Intermediate terminating facilities are provided at Sunshine, St Albans and Watergardens. Stabling facilities are provided at North Melbourne, St Albans, and Sydenham.
