It was the junction of the Sedan and Wolseley lines.

[1] On 13 October 1919, Monarto South became a junction station with the opening of the Sedan line.

[4] This ceased when the Sedan line was also converted as far as its then terminus at Apamurra in November 1995.

[5][6][7] After standardisation, the station was demolished with the station building being preserved at the Old Tailem Town Pioneer Village.

The yard used for grain trains have fallen into disuse and trucks now transport grain from the silos, but a 1,550 metre crossing loop remains in use.
