YOU CAN'T HEAR A TREE GROW H Amid all the headlines and ex citement about the radical new, ex perimental trains, this stainless steel, self-propelled, rail diesel car-RDC -has been revolutionizing rail passenger transportation. There is nothing unproved about RDC. It has traveled a hundred million miles. Twenty-nine railroads, here and abroad, have bought three hundred RDCs. Everywhere they have provided passenger-enthusiastic service. They have proved a practical alternative to abandonments. They have restored rail service to communities that had had none for years. They have saved their railroad owners millions of dollars. This year we have given RDC a "new look" . . . built into it all that vast operating experience, invention and new materials have accumulated during its six brilliant years. Rail roads have already ordered more than sixty of these new RDCs. The Budd Company, Philadelphia 15.
