sentences:  In 1869 the Indianapolis, Bloomington and Western Railway was built across Mound Township in the southern part of the county.A few years later, in 1872, a branch of the Chicago, Danville and Vincennes Railroad (known as the "Pumpkin Vine Railroad") was built from Bismarck, Illinois, southeast through Warren County; it was built specifically to carry coal from the mines south of Covington.A labor riot at the mines in the late 1870s interrupted the flow of coal, and this combined with the poor financial state of the railroad led to the removal of most of the track by 1880; the remaining portion was removed a few years later.
