Other major resource activities supported by the town include the offshore natural gas fields, salt, manganese, and livestock. Major deposits of lithium are being developed and exploited south of the town as well. Grazing of cattle and sheep was formerly a major revenue earner for the region, but this has slowly declined. Port Hedland was also formerly the terminus for the WAGR Marble Bar Railway, which serviced the gold mining area of Marble Bar from July 1911 until closure on 31 October 1951. The locomotive from the Port Hedland to Marble Bar rail service is now preserved at the Kalamunda Historical Village in the south of the state.
