The act contains twenty-four sections, but is by no means cumbersome. It is, in many respects, the most important piece of legislation that has been had in Congress for the past twenty years. It applies to common carriers engaged in the transportation of passengers or property wholly by railroad, or partly by railroad and partly by water, when both are used, under a common control, management or arrangement, for a continuous carriage or shipment from one State or Territory of the United States, or the District of Columbia, to any other State or Territory in the United States or the District of Columbia, or from any place in the United States to an adjacent foreign country, or from any place in the United States through a foreign country to any other place in the United States. It prohibits unjust and unreasonable charges, special rates, rebates, drawbacks, undue or unreasonable preferences, advantages, prejudices and disadvantages, as well as all discriminations between connecting lines. It makes unlawful a less charge for a longer than for a shorter haul over the same line, in the same direction, the shorter being included within the longer distance, except when specially authorized by the Interstate Commerce Commission. It prohibits pools, requires schedules of freight rates and passenger fares to be kept in all depots and stations, permits no advance in the rates, fares and charges once established, except after ten days' public notice, and makes it unlawful for common carriers to charge either more or less than schedule rates. It also requires them to file copies of all schedules, traffic contracts and joint schedules with the Interstate Commerce Commission, as well as to make them public when directed by the commission, and prohibits combinations to prevent the carriage of freight from being continuous from the place of shipment to the place of destination. It makes common carriers liable for all damages to persons injured by violations of the act, and specially provides that any court before which such a damage suit may be pending may compel any director, officer, receiver, trustee or agent of the defendant company to appear and testify in the case, and that the claim that any such testimony or evidence may tend to criminate the person giving such evidence shall not excuse such witness from testifying, but that such evidence or testimony shall not be used against such person on the trial of any criminal proceeding. It likewise subjects such officers and employes of a railroad company as may be guilty of aiding or abetting in violations of the act to fines not exceeding $5,000 for each offense.
