Environmental Condition Monitoring (ECM) measures wayside environmental conditions.

Safe Railway Operation by Measuring the Current Environmental Conditions

Railroad operators must ensure safe and reliable operation in any environmental conditions. The ECM offers various sensors that provide current weather data in real time. Especially at bridges and open aisles, strong crosswinds occur from time to time, which can endanger safe train passage. Installed in tunnels, the sensor system provides airflow direction, which in the event of a fire informs the rescue team of the direction in which the smoke and toxic gases are drifting. Passengers are also evacuated in the tunnel along the safest route based on this information.
