The North Shore Line was opened on 1 January1890 as a single track between Hornsby and St Leonards. The line was extended to the Sydney Harbour foreshore at Milsons Point on 1 May1893. Transport between this original Milsons Point station and central Sydney was by ferry boat. Most of the North Shore line was duplicated between 1900 and 1909. In 1927 the line was converted to electric operation using a 1500 volt DC, overhead supply.
The construction works for the Sydney Harbour Bridge necessitated truncation of the southern terminus from Milsons Point to Lavender Bay.
When the Sydney Harbour Bridge was opened in 19 March1932 a new Milsons Point station (on the bridge approach) came into operation and the North Shore Line was extended through it and over the Sydney Harbour Bridge to link with the underground lines of central Sydney. The result is that the two ends of the North Shore Line link to the Sydney railway system at Central and Hornsby.
After 1932 the original Lavender Bay station became a storage depot for electric trains, and the line connecting Lavender Bay to the North Shore line was reduced to single track. This line joins the current passenger-carrying North Shore line at Waverton station.
The NSW Government Urban Transport Statement identifies capacity and service improvements for the North Shore Line with plans to add extra tracks between Gordon and Chatswood, and extra platforms at St Leonards by 2017. 1
