The Sishen–Saldanha railway line, also known as the Ore Export Line (OREX), is an 861-kilometre-long (535 mi) heavy-haul railway line in South Africa. It connects iron ore mines near Sishen in the Northern Cape with the port at Saldanha Bay in the Western Cape. It is used primarily to transport iron ore (60 million tonnes per year) and does not carry passenger traffic.

Saldanha Bay is a natural harbour on the south-western coast of South Africa. The town that developed on the northern shore of the bay, also called Saldanha, was incorporated with five other towns into the Saldanha Bay Local Municipality in 2000. The current population of the municipality is estimated at 72,000.
