The paper deals with the fundamental principles of modern brake equipment design, using as a theme the generation, transmission, and interpretation of the brake demand signal. The limitations of conventional systems using air as a transmission medium are briefly stated, showing the necessity for the adoption of electrical control to achieve the performance required from a modern brake control system. Electrical brake control systems fall into two categories, the so called "All Electric" arrangements where the electric demand transmission system provides the only brake communication path down the train, and the combined "Electric-Pneumatic" arrangements where electrical control is superimposed onto an otherwise conventional pneumatically controlled brake system. The paper considers the relative merits and applications of the two concepts, and goes on to discuss the various alternative electrical demand transmission systems in current use.
