Since two tracks had already been laid down the middle of Ellen Street to the wharves, a small corrugated iron shed was erected as a ticket and parcels office.
However, after 1888 the line also moved large amounts of silver-lead-zinc ore to Port Pirie from the New South Wales border near Broken Hill, 351 km (218 mi) away.
Since the smelters had been built next to the northern end of the wharves, Ellen Street saw most of the inwards freight tonnage for Port Pirie, and sulphuric acid (a by-product sold to a fertiliser factory) outwards.
It was into this busy scene that the SAR decided, in late 1900, to introduce an on-street station for passenger services 400 metres (440 yards) short of the smelter gates.
In 1937, one of the two narrow-gauge tracks in Ellen Street was modified to dual gauge for broad-gauge trains connecting with Adelaide on a new, much more direct route via a line from Redhill.
[7] Like four of Port Pirie's six railway stations, Ellen Street was superseded as a consequence of lines being constructed to wider gauges eventually entering the city.
From 1970, when a standard-gauge line from Sydney via Broken Hill would be completed, a 213-metre (700-foot) platform would be necessary to provide for passengers on far longer trains to transfer across between broad and standard gauge.
[9][5][10] Externally unaltered since its erection in 1902, the building retains its prominent place in Port Pirie as a National Trust of South Australia museum, 57–58 years since it closed as a station.
