LOAD-TO-TARE RATIOS VS. BRAKING

This second installment traces the evolution of the air brake as steel replaced wood in freight cars, and both individual car capacities and train lengths grew. Following passage of the Safety Appliance Acts of 1893 which required power brakes eventually on all cars, passenger and freight brake systems began to evolve on different paths. The more highly sophisticated passenger brake system developed control features which were gradually incorporated in freight equipment. Traced here are development of the Types H, L, K, and AB freight brake systems, the empty-load brake and the PC, Universal, and electro-pneumatic equipments for passenger service. Period covered in 1890 to 1930.
