From these modest beginnings the development of classification in the United States was rapid, responding to the ever-increasing intensity of competition and the spread of markets, particularly after 1875. By the middle of the eighties most of the large railways were working under six or eight different classifications. It began to be apparent that some check must be placed upon such increasing complexity. For conditions were wellnigh intolerable, with one set of rules for Illinois, and yet another west of Buffalo, divided into eastbound and westbound sections, with still a third on westward shipments local to territory between Chicago and the Missouri river. The first attempt at a systematic scheme was made in 1882, but the agreements then made proved unstable. By 1887 conditions had become insupportable, so great was the number and the diversity of the classifications throughout the country.[324] Some applied to local business only, and were peculiar to each road. Some applied only to westbound business, others to eastbound traffic. The traffic manager of the New York Central & Hudson River testified before the Interstate Commerce Commission that there were at one time 138 distinct classifications in trunk line territory alone. The case of the Wabash in 1883 was typical. A shipper desiring to determine freight rates over that road might be compelled to consult a classification for the middle and western states in six classes; one for the Southern Railway & Steamship Association territory in eighteen classes; one for Mississippi valley business in five classes; one known as the Revised Western in nine classes; the Trunk Line East in thirteen classes; the Trunk Line West in five classes; a classification for Texas points in eight classes; and two for the Pacific coast, according to direction, in eight and nine classes, respectively. This situation, rendering it almost impossible for any shipper to determine in advance what his freight rates were going to be, as well as what his competitor was paying, early impressed itself upon the Interstate Commerce Commission. And it was doubtless due in part to its initiative that classifications were shaken down into substantially their present general form in 1888.
