"This Scotch-type marine boiler has just crossed the grand Trunk Railroad main line as it travels on a dolly and rails from the Portland Company boiler shop to the company pier. The Portland Company maintained a right-of-way across the railroad's tracks to move equipment, materials, and employees to its pier, where the customers' vessels were equipped or repaired." - Fletcher, David H. ' The Portland Company 1846-1982.' Charleston, S.C. : Arcadia Pub., 2002. 73.
