A rail-vehicle mounted system (10, Fig.1) comprises a sensor unit 20 directed at a track 32 ahead of the vehicle 30 in the direction of motion. The sensor data may be LIDAR, SONAR or video data, and is analysed in real time to indicate track conditions. E.g. image analysis may detect objects on the track, a direction in which the track is proceeding, a status of railway points 34 or a track defect. If an object is detected, an emergency system may sound an alarm or apply brakes. The detected track direction may be used to anticipate track layout, e.g. speed modulation. Once the train’s future path is determined (e.g. using the points setting indicated by point tips (switch plates) 38, Fig.2C) a directional alarm can protect a region in the direction it will travel while ignoring other directions. The information may be communicated to other nearby systems or a central information store. Information received from them may be confirmed or updated.
