Diesel locomotives with mechydro hydraulic transmission for lightweight passenger trains

FOR MANY YEARS the railroads have been operating their passenger business at a loss, and although they have studied this problem, to date they have not succeeded in reducing this loss appreciably. The locomotive and passenger-car builders have also been considering this problem in an effort to help the railroads turn the loss into a profit. In the last year they have put the results of their study into action by designing and building a new type of passenger car. These cars are lower in initial cost, lighter in weight to reduce the power required to haul them, have a lower center of gravity to permit greater riding comfort and more speed when going around curves, and have been designed to require less maintenance. The cars represent a marked change from designs that preceded them.
