This map shows the Expansion of the Railroad System from 1850 to 1890. The map key shows the railroad growth in four stages: rail lines in 1850, rail lines in 1860, rail lines in 1870, and rail lines from 1870 to 1890. As the map indicates, in 1850, the United States had 9,000 miles of rail track, primarily up and down the East Coast of the U.S. and around the Great Lakes on the upper peninsula of Michigan; rail lines in the 1860 began to fill in further areas around the early lines and expand slightly toward the Mississippi River, by the 1870s, more lines were built into the West targeting cities like Omaha, Salt Lake City and San Francisco. By 1890, railroads had expanded to 167,000 miles, including transcontinental lines terminating in Los Angeles, and Seattle. The tremendous burst of construction during the last twenty years of that period essentially completed the nation’s rail network, although there would be additional expansion for the next two decades. The main areas of growth were in the South and in lands west of the Mississippi. Time zones — an innovation introduced not by government entities, but by railroad corporations in 1883 — are marked by the gray lines on this map.
