The dataset contains accelerometer recordings over a period of approximately 2 days. There are 27 annotated train passings over the point where an accelerometer sensor was installed. Each line of the dataset follows the following format: [time since first epoch], microseconds, X, Y, Z Each line in indices.txt indicates the timing a train arrived at the point of measurement. This dataset was published along with the following paper: D. Zorbas, M. Baizhuminova, A. Eduard, D. Urazayev, G. Nurgazina, N. Atymtay, M. Ristin, "Cost-Effective Train Presence Detection and Alerting Using Resource-Constrained Devices", Sensors, MDPI, Sep. 2025
