concerned.[381] One of the primary advantages, therefore, from the unification of the three systems now existing, would be the possibility of readjusting not only definitely, but also equitably, the conflicting interests of various shippers and communities now tied up by these local arrangements. A recent case[382] illustrates the bearing of classification rules upon competition in trade as between rival cities. Chicago and most of the Ohio river gateways enjoy a so-called "two-for-one-rule," permitting the application of carload rates on part carloads in excess of full car ladings. The complaint alleged that the denial of this privilege to Indianapolis, whereby less-than-carload rates were charged on excess fractional carloads, unjustly discriminated against this city in the transportation of various light and bulky articles, such as vehicles and furniture, in competition for trade throughout the Southwest. The difficulty arose from a conflict between rules in the Western Classification and the Southwestern Tariff Committee, the latter being a subordinate body having jurisdiction over local practices in Texas and the neighborhood. The rule in one case provided that where a car of sufficient capacity to accommodate light and bulky shipments could not be promptly furnished, two smaller cars would be provided, subject to wholesale rates, however the consignment was divided between the two cars. The Commission declined to interfere in this case, anticipating the necessity for a thoroughgoing revision of all such rules which, it is obvious, almost invite manipulation of rates and improper discrimination.
