Abstract
The paper presents a new approach to railway traffic analysis.Track occupation data is used to reconstruct the speed profileof the train and in a second step its energy consumption.The speed reconstruction algorithm is based on non-linearleast squares optimisation and a simplified model of trainmotion. The engineering effort to make this method broadlyapplicable is presented as well as the train model which isused to derive energy consumption. The application of thealgorithm is shown by means of a case study for a 180 kmlong Intercity line, where the results have been verified usingGPS data and energy measurements.
