Abstract
A GREAT MANY PEOPLE in the financial community today know what centralized traffic-control signaling is and what it does to increase train speeds and safety and promote railway operating efficiency. Also, the knowledge that great operating economies can be secured through mechanized freight-classification operations using car retarders has become widespread among promoters of better railroading. Interest in yard improvements has been appreciably advanced in the last year or two because of greatly improved car-retarder systems and by a continuing discussion of the subject in the technical press. As a typical result, loaded cars that once spent some 20 hours in yards now spend 8 hours of their respective runs in classification yards. (A good example of a really modern yard is at Bensenville, Ill., on the Milwaukee Railroad.) TIhere are many instances where the running time of freight trains has been reduced by as much as one minute per mile of CTC in service. With the combination of CTC and car retarders, road time and yard time can be reduced and the interval between loading and unloading time of cars substantially lessened, resulting in more effective use of equipment.
