Both of these systems are in successful use, andboth can no doubt be designed and constructed to give satis-factory service in the zone. of the operating divisions of the railroads. A study of arailroad system as a whole, even if it lay entirely within thezone, would yield only average results, which might make apoor showing, whereas some of the divisions treated sep-arately might make a good showing. It was, therefore, de-cided to ask each of the Class 1 railroads within the super-power zone, of which a list is given above, to answerquestions asking for certain funda-mental data as to roadbed, equip-ment and traffic.
