@metrolinktrains: 🌎 Earthquakes can happen without warning. But Metrolink has a plan. By combining ShakeAlert earthquake detection with Positive Train Control (PTC), our advanced safety system can automatically slow or stop trains when an earthquake strikes. Deputy Chief Operating Officer Luis Carrasquero explains how this technology helps protect our riders when every second counts. A good reminder on Great California ShakeOut day.
