Nebraska's Cowboy Line existed for nearly 125 years and covered more than 400 miles as it made its way across the northern portion of the state. The construction of the rail line, which started in 1869, was the impetus for the establishment of many towns, and even the relocation of some, along the route. The line was employed to transport miners to the Black Hills during the gold rush of the late 1800s, it carried thousands of Irish and German immigrants to the largely unsettled area, and it allowed politicians to meet their constituents. It also was used to deliver necessities, amusements, technology, and new innovations to the state's citizenry.
