The location of Dunlap was within the final 50 miles of the railroad's Council Bluffs goal, connecting with the Union Pacific's transcontinental railroad building from Omaha. By January 1867, the engineering had been completed to Council Bluffs[6] and by April 30 the first trains would be able to run all the way through, making this the first uninterrupted rail connection with the East.[7] So with the concurrence of John B. Turner, former Pres. and Director of the C&NW, on Feb. 13, 1867 George L. Dunlap wrote Isaac B Howe, Supt. of the Iowa Div.: "(Dunlap is)...the proper point for terminus of the Division, ...locating a town there and establishing comfortable homes for our men, thereby attaching them to the Co.'s interest and increasing their efficiency."

If it is as you state, that Messrs Blair & Walker do not own the land when we propose locating at "Dunlap", and cannot set up any claim that will conflict with our interests, you are authorized to make all the necessary arrangements with Judge Dow for the proper camping out of the plan your letter indicates. I have read your letter to Mr. Turner who is chairman of our committee, and he concurs with me as to "Dunlap's" being the proper point for terminus of the Division, and he approves the suggestion of locating a town there and establishing comfortable homes for our men, thereby attaching them to the Co.'s interest and increasing their efficiency.
As soon as your land arrangements are completed with the Judge, I want you to secure bricks and material for an engine house at Dunlap, and let the work be commenced in the spring as soon as the weather is suitable. And you will also secure bricks and material for an eleven stall engine house, and suitable blacksmiths and car shops at Council Bluffs to be commenced as soon as ever the post gets out enough to permit us. Do not fail to secure the spring at "Dunlap"; and I want you to fix for building the dam at Boone, below the engine house to insure a constant supply of water at the situation."
