For nearly 150 years, a short ribbon of railway between Central Station and Darling Harbour was the main artery of Sydney.

Most of the city's commerce and the wool, meat and wheat brought in and out of the city for sale trundled along the Goods Line, which connected the city to Darling Harbour and everything to its west.

That link has lain largely dormant and disused for decades.
