Method for Evaluation of the Actual Utilisation of the Train Maximum Speed

The aim of the research is to establish method for evaluation of actual utilization of the maximum line speed. Another goal is to identify factors influencing utilization of the maximum line speed in case of long-distance passenger trains on the Polish railway network. The extensive database covering the infrastructure data and rolling stock data for long-distance train services in Poland has been compiled. On infrastructure side main factor seems to be differentiation of the maximum speed along the line, which is taken into account with the harmonic weighted mean. As far as rolling stock is concerned main factors are type of train formation (loco-hauled, EMU) and power-to-weight ratio. Also impact of track works on speed utilization has been studied. The best utilization of maximum line speed is in the case of long sections passed without intermediate stops, at which the influence of acceleration and braking is relatively minor. The utilization of maximum speed is negatively influenced by significant differentiation of the speed profile (frequent and large changes of speed along the line).
