Waterways is a river port, and was then the northern terminus of the North American railway grid.

A 16-mile series of large rapids at Fort Smith, NWT, on the Slave River, required a long portage.

Most of the vessels of the Radium Line were reassembled at waterways, sailed to Fort Smith, then portaged overland to the lower river, and where they could navigate most of the tributaries of the Mackenzie River, and reach the Arctic Ocean without further portages.
