Abstract
Advances in railway telematics and the large amount of data obtained from train services enable the development of methods that are capable of further improving energy efficiency through the evaluation, control or prediction of energy utilisation of the railways. The paper proposes a method for determining the longitudinal running resistance of electric trains based on the measurements of on-board telemetric units of the locomotives. The purpose of the algorithm is to resolve the parameters of the commonly used polynomial resistance formula for specific locomotive and rolling stock types. In contrast with the classic measurements, such as tractive effort, dynamometer or drawbar and the coasting methods, the algorithm uses data from actual train runs, hence there is no need for closed test tracks or special measurement scenarios, although, naturally, the measurement conditions, such as track inclinations and rolling stock loads, must be known.
