 The line between St Leonards and Milsons Point (the terminus) was built as double track and both Wollstonecraft and Waverton stations were built to suit the duplicated track from the outset.At the time of opening, Waverton railway station consisted of two side platforms (for Up and Down North Shore lines), with a small timber station building on each of the platforms.Bay Road tunnel (and Lavender Bay tunnel) were both built during construction of the line between St Leonards and Milsons Point and opened for service as double track tunnels in 1893.
