Abstract :
FOR MANY YEARS the railroads have been operating their passenger business at a loss. The railroads, as well as locomotive and car builders, have studied this problem to see what could be done to turn the loss into a profit. The findings of the study have resulted in designing and building a new type of passenger car and locomotive. The cars are lower in initial cost, are lighter in weight and require less power to haul them, have a lower center of gravity, and have been designed to require less maintenance.
