Abstract
One way to increase the throughput and carrying capacity of railways consists in the use of freight trains with an increased weight and length. In order to improve traffic safety, automatic speed control systems (ASCSs) are used for controlling such trains, taking into account the distinctive features of processes occurring in a train. There is a well-known ASCS that provides acceleration (braking) a train with changing traction force or braking force in two stages. This reduces the longitudinal dynamic forces that occur in the train, but in some cases leads to delaying transient processes. An improved ASCS is proposed, wherein, depending on the level of stretching (compression) of a train before starting acceleration (braking), the acceleration (braking) mode is automatically chosen in one or two stages. The use of one-stage train acceleration leads to an increase in the throughput capacity of railways and in saving energy resources for train traction.
