North Sydney railway station is a CityRail station which lies on the North Shore Line and the Northern Line, 5.1 km from Central Railway Station, Sydney, Australia. It serves the major employment centre of North Sydney and is the fourth busiest railway station in NSW.
The four platforms at North Sydney can have different usages, but the outer platforms are generally the only ones used in off-peak; the middle platforms generally serve terminating trains arriving from the city. Because the four platforms at North Sydney serve a double track railway to the north and south of the station, it has significant capacity for terminating traffic. Up to six trains are stabled in the middle road tunnels at North Sydney and up to six trains may be stabled in the nearby sidings at Lavender Bay during the day. The station is served by six trains per hour each way, with additional trains during weekday peak hours.
