On Sunday evening, heavy rainfall led to flash flooding in Cootamundra and surrounding regions.
Following the rainfall, ARTC conducted track inspections and discovered a section of track had been washed away at Stockinbingal on the branch line.
The track was closed for repair and reopened at 1200 on Thursday 16th March.
A temporary speed restriction is now in place for 500 metres of track.
The East West and North South lines remain open.
