COMPARATIVE ANALYSIS OF THE BRAKING MODES OF THE ”SIEMENS INSPIRO SF” METROTRAINS AND TYPE 81 METROTRAINS OPERATED IN THE SOFIA METROPOLITEN

Atanas Dyakov, Vasko Nikolov

The report presents a comparative analysis of the types of brakes and braking systems equipped with the ”Siemens Inspiro SF” metro trains and trainsets with metro cars of the ”81” series. The comparative analysis of braking modes and types of brakes used in metro trains operated on the four lines of the Sofia metropolitan was made, considering their technical data, specifications and characteristics. The period of their production, as well as their modification over time, covering the main criteria of modern ments for lightness of vehicles, higher power, more energy saving, vision, comfort and greater capacity of passenger cars is also consistent. The speed at which metro trains stop at a final standstill under normal operating conditions, without system failures, breakdowns and accidents, has been examined, compared and analyzed. The types of braking modes that hold and secure the train against rolling during the multiple short-term stops are also summarized and compared. The topics of the systems and types of management, monitoring and control of the movement of trains, as well as the actuation of the emergency brake in cases of emergency or other extreme stops of the railway vehicles, were considered.
