From the time when the Sydney Railway Company was formed in 1848, it had been the intention of the company to build a freight terminal at Darling Harbour. To this end, a railway line was constructed between the Sydney Railway Station (the predecessor to Central railway station) and Darling Harbour, which opened on 26 September 1855. Initial traffic was spoil for the construction of the Main Suburban line (now the Inner West line) between Sydney and Parramatta, then for the carriage of departmental coke for steam engines, and a small amount of timber from 1860. Initial reports of the traffic on the line suggested that freight revenue amounted to only £20 a year, and there was only 60 tonnes of coke carriage a week.
