The ore is transported from the mine to a connection with QNSL at Wabush, NL by Arnaud's sister railway, the Wabush Lake Railway. QNSL transports the ore between Wabush, NL and Arnaud Jct., QC. At Arnaud Jct., the ore is transferred to Chemin de fer Arnaud for the final journey to Pointe-Noire, Quebec.
Currently, this railway (along with the TSH line, QNSX, and WABL) form an isolated railroad network, as it does not directly interchange with any other rail lines on the North American network at this time, aside from rail ferry service via COGEMA to the CN Rail port at Matane, Quebec.
