Abstract: “The braking is one of the most important duty cycles of a rail vehicle , irrespective of the type of the vehicle, i.e. a classical or a high speed one, due to the traffic safety that it must ensure and to the great diversity of factors that may influence its function. The electrical braking (with rheostat or regenerative) is characteristic for the rail stock motor vehicles and is based on the principle of reversibility in the electrical equipment. The authors present in the paper a solution obtained as a result of experiments on the electrical braking system for vehicles with frequent starts and stops. The experiments consisted in the replacement of the electrical braking system produced by an independent excitation generator with one produced by a series excitation generator”
