On-Board Units (OBUs): The intelligent core of train control
On-Board Units (OBUs) are the vital, intelligent computer systems installed directly on trains, acting as the “brains and eyes” for modern Train Control Systems. As an integral component of advanced systems like the European Train Control System (ETCS), OBUs are essential for enabling dynamic, real-time communication between the train and the trackside infrastructure.
