Pneumatic tired diesel electric rail car

DIESEL electric rail car having a body of stainless hi-tensile steel construction and running on pneumatic rubber tires has recently been delivered to the Reading Company. Much fundamental development work in the building of this 47-passenger car was done by the E. G. Budd Manufacturing Company, involving the forming and handling of thin sheets of steel, and requiring considerable research into methods of welding. As the result of this work the weight of a self-propelled car of a given seating capacity has been reduced to 33 per cent of the weight of the accepted passenger coach having no power as used on Class I roads
