There seems to be no doubt but what the railroads can and do transport large quantities long distances quicker, better, and more efficiently than can be done on the highways. Highways may be considered as feeders of the railways. With good roads the zone from which the railway can profitably draw products for long distance or quantity transportation is widened, and again widened very materially when better roads allow the use of motors in place of horses. This, if no other railway interferes, means a larger grand total of traffic hauled. Again the character of the farming along the zone served by a railroad will depend upon the facilities for marketing as well as soil and climate. Those products ordinarily called perishable may be raised if the roads are good so that they may be marketed quickly and cheap enough to compete with other localities. Such produce yield a larger net return per acre than the staple grain products. Intensive farming is usually necessary in such cases so that a smaller farm will support a family allowing an increase in rural population, a thing most highly desirable in this country. The railroad benefits again, then, because of the increased produce raised by intensive farming brought about by quick marketing facilities, and by increased freight and passenger traffic necessary to supply the greater population. Furthermore, if roads were good throughout the year marketing would be spread over the entire period and there would not at times be a glut with corresponding scarcity of cars, and other facilities for handling. If cars, warehouses and elevators were sufficient to care for these periods there would be an over supply of facilities at other times and capital would be unnecessarily tied up producing larger overhead charges. With good roads there would likewise be less need for large quantities of money at particular periods of the year as uniform marketing would allow a smaller capital to be turned oftener. Moreover, unproductive branch lines would by the increased traffic brought to them by the improved highways be either made productive or they could be dispensed with altogether. The unproductive short-haul traffic would then be cared for by electric railways, motor trucks or even by horse wagons. =Intra City Traffic.=--Mr. J. C. Thirlwall, of the railway and tractive engineering department of the General Electric Company (_General Electric Review_, Vol. XXIV, pp. 974-985), discussing the fields of the rail car, trolley bus and gasoline bus, tabulates the respective costs of these types on a comparative basis for a variety of conditions. In general the calculations indicate that: (_a_) Where rush hour headways of 3 min. or less are required with safety cars, rail cars are the most economical and up to 6 min. headways offer successful competition to the other types where the road is a going concern.
