Indiana, Historical Profile (1919), #008-Transportation
Indiana is traversed in all directions by a large number of trunk lines of railway, which have their western centers in Chicago and Saint Louis and their eastern centers in New York, Philadelphia, Baltimore and other large cities. With the exception of the two southern tiers of counties, all portions of the state are well supplied with railway facilities, bill owing to the uneven- ness of the land in the region named only a few lines have been constructed there. The entire mileage of the state exceeds 7,500 miles, and in addition to this there are 2,350 miles of electric lines. Indiana has joined all important cities with a network of interurban lines, and Indianapolis has the largest interurban station in the world. The Ohio is the only navigable river which is of value to the state as a means of transportation.
