 The station opened on 17 September 1886 as Hornsby, but was renamed Hornsby Junction on 1 November 1894.This was due to the construction of Normanhurst station to the south, which was initially named Hornsby as it was located in what was the more densely populated area of Hornsby at the time.Naming the station Hornsby Junction was an attempt to avoid confusion, but it was realised that having two Hornsby stations was still very confusing.
