| McKee was a contractor who built plants for the wartime Defense Plant Corporation. These two locomotives most likely were used at Indiana Harbor IN to build a major expansion of the Inland Steel facility. After the war, they were transferred to Inland Steel ownership as 67 and 68, and it is presumed the Alcos were scrapped or converted to slugs. (Info from Andre Kristopans and Larry Russell) | ||||

| Locos were lettered DPC #1001 & 1002. The two units were apparently used to build the Holabird Ordnance Depot at what before the war was Ft Holabird (and later reverted to that name again) in Maryland. The 1001 later became USAF 7370 at Griffiss AFB, Rome NY. The 1002 was re-#d US Army 7371 then donated to Western Pennsylvania RR Historical Society, and lastly to Ashtabula Carson & Jefferson Railroad 7371. | ||||
