The Nebraska-Kansas Railroad was owned and operated by the Ideal Cement Company at its plant near Superior, Neb. This small industrial railway, about four miles long at maximum length, crossed the state line from the cement plant in Nebraska to the company's rock quarry in Kansas. Hauls of the N-K Railroad were almost exclusively limestone rock for use in the manufacture of cement at the Superior plant. The line achieved national fame when "Ripley's Believe It or Not" cited it as being the shortest interstate railroad in the U.S. The N-K, which at various times used electric, steam and diesel power, operated until the end of cement production at the Superior plant in 1986.
