To supply a central smelter, Moffat needed a network of railways to his mines. He had commissioned the survey of a railway route to Chillagoe in 1892, hoping for a land-grant railway, but the depression had stifled the proposal. The Queensland Government's railway from Cairns reached Mareeba in the early 1890s and Moffat hoped to build a railway inland from this point. However, he needed capital for such a venture, and in 1897 he went to Melbourne to find investors, where he gained the attention of Charles William Chapman and James Smith Reid. In 1897 the Chillagoe Proprietary Company was formed. Reid and Chapman accompanied Moffat to Brisbane in November 1897 to present their railway proposal to the government. The resultant Mareeba to Chillagoe Railway Act of 1897 empowered the Chillagoe Proprietary Company to build a railway for , subject only to a government right of purchase after 50 years. In 1898 a new company, Chillagoe Railway and Mines Limited, was formed to take over the assets of the Chillagoe Proprietary Company.
