Chapter One: Picking the Route 1830-1860
August 13, 1859, was a hot day in Council Bluffs, Iowa. The settlement was on the western boundary of the state, just across the Missouri River from the Nebraska village of Omaha. A politician from the neighboring state of Illinois, Abraham Lincoln, went to Concert Hall to make a speech. It attracted a big crowd because of Lincoln's prominence after the previous year's Lincoln-Douglas debates and the keen interest in the following year's presidential election. Lincoln was a full-time politician and a candidate for the Republican nomination for president. The local editor called Lincoln's speech -- never recorded -- one that "set forth the true principles of the Republican party."
In the audience was Grenville Mellen Dodge, a twenty-eight-year-old railroad engineer. The next day he joined a group of citizens who had gathered on the big porch of the Pacific House, a hotel, to hear Lincoln answer questions. When Lincoln had finished and the crowd dispersed, W.H.M. Pusey, with whom the speaker was staying, recognized young Dodge. He pointed out Dodge to Lincoln and said that the young engineer knew more about railroads than any "two men in the country."
That snapped Lincoln's head around. He studied Dodge intently for a moment and then said, "Let's go meet." He and Pusey strolled across the porch to a bench where Dodge was sitting. Pusey introduced them. Lincoln sat down beside Dodge, crossed his long legs, swung his foot for a moment, put his big hand on Dodge's forearm, and went straight to the point: "Dodge, what's the best route for a Pacific railroad to the West?"
Dodge instantly replied, "From this town out the Platte Valley."
Lincoln thought that over for a moment or two, then asked, "Why do you think so?"
Dodge replied that the route of the forty-second parallel was the "most practical and economic" for building the railroad, which made Council Bluffs the "logical point of beginning."
Why? Lincoln wanted to know.
"Because of the railroads building from Chicago to this point," Dodge answered, and because of the uniform grade along the Platte Valley all the way to the Rocky Mountains.
Lincoln went on with his questions, until he had gathered from Dodge all the information Dodge had reaped privately doing surveys for the Rock Island Railroad Company on the best route to the West. Or, as Dodge later put it, "He shelled my woods completely and got all the information I'd collected."
The transcontinental railroad had been talked about, promoted, encouraged, desired for three decades. This was true even though the railroads in their first decades of existence were rickety, ran on poorly laid tracks that gave a bone-crushing bump-bump-bump to the cars as they chugged along, and could only be stopped by a series of brakemen, one on top of each car. They had to turn a wheel connected to a device that put pressure on the wheels to slow and finally to stop. The cars were too hot in the summer, much too cold in the winter (unless...
