 The signalling in the vicinity of Waverton was then controlled by North Sydney signal box.With the opening of the Sydney Harbour Bridge in 1932 and construction of new stations at North Sydney and Milsons Point on a much higher level (to suit the bridge arrangements), the trackwork at Waverton was substantially altered.The original line which was laid down the grade, through the Lavender Bay tunnel to the original Milsons Point station at Lavender Bay became a branch line.
