The original Mulgrave station opened on 1 December 1864 coinciding with that of the Richmond line. It was relocated east to its present site in 1912. In 1939, it was converted to an island platform with a passing loop added.[3][4]
Historically,[when?] Mulgrave has been served by services operating from Sydney CBD/North Shore, branching off the Western Line at Blacktown. However, after a major timetable change for the Sydney Trains network on 26 November 2017, Cumberland line services started continuing out to Richmond, rather than terminating at Schofields, during the late night, taking over from the Richmond line at these times.
