U.S. Naval Base, Pearl Harbor, Marine Railway No. 2 Machine House & Substation, Near intersection of Avenue G & Third Street, northwest of Dry Dock No. 3, Pearl City, Honolulu County, HI

Significance: It functioned as the winch for the Marine Railway No. 2, which was a repair cradle for Pearl Harbor. The Marine Railway No. 2, with its rails, cradle, and superstructure of steel beams and steel girder cross members, was a breathtaking piece of work. The Machine House still has integrity, but, unfortunately, its counterpart, the Marine Railway No. 2, has been demolished. It is associated with the expansion of the Navy Shipyard during WWII.
