 In spite of the name, the Peterborough section of the line was not used, however, a new stretch of line from Blairton to Trent River was constructed.Ore was loaded onto barges on the Trent then hauled up the Trent and across Crowe Lake to the dock in Blairton.The ore was then driven the short distance to Trent River, where the bottom-opening cars would dump the ore into new barges.
