The triweekly QGRY run on the Lachute Subdivision crosses over the Little Nation River in Plaisance. Shortly, the train will arrive in Thurso where it will exchange cars with a locally-based crew that spent the day assembling outbound loads from the industries in Thurso, Buckingham, Masson and Gatineau. When the swap is complete, they will return to home base at Ste-Thérèse.
