Major-General D. C. McCallum: an officer praised by General GrantOn September 14, 1863, General Haupt was relieved from further duty in the War Department, and turned over his duties to Colonel (later Major-General) D. C. McCallum, who was appointed Superintendent of Military Railroads. The efficient operation of the roads with the Army of the Potomac continued, and received the enthusiastic praise of General Grant. Engines for the military railroad at City Point had to be transported by water. In the lower photograph the “General Dix” is seen being landed at City Point. This engine weighed 59,000 pounds and cost $9,500. It was credited with a record of 16,776 miles at the comparatively low cost of $6,136.62 during the fiscal year ending June, 1865. Behind it is the tender piled up with the wood which was used for fuel in those days. This is what necessitated the gigantic stacks of the wood-burning engines. The “General Dix” has evidently been put into perfect condition for its trips over the uneven track of the railway from City Point to the army lines at Petersburg.
