ELECTRIC BRAKING IS ESSENTIAL: HISTORY AND ADVANTAGES OF ELECTRIC BRAKING: TECHNOLOGY AND PERFORMANCE

In the first article, the author, who is Rolling Stock Manager of the SNCF, explains the functioning of electric braking, its development and how it is employed. He lists its various advantages and states that electric brakes are essential for speeds above 180 km/h. High-speed running experiments have therefore produced a new technology in this field. The author refers to the economic benefits of this braking system and concludes by describing the developments which, by employing electronic power-control systems, have led to present applications. In the second article, the author, who is Head of the Electronics Division at the SNCF Rolling Department, gives details of the SNCF electric motive power fleet fitted with electric brakes, which are essential for high-speed running. The characteristics and operation of electric braking equipment are described on the most modern direct-current, single-phase and dual-current locomotives (CC 6500, BB 7200 BB 15000 and BB 22200 series), as well as on the experimental high-speed Z 7100 railcar. The locomotives have two different electric brake systems (one for normal braking, the other for emergency braking); the railcar is provided with an eddy-current linear brake system.
