The Shift to Centralized Signaling: Siemens Demonstrates “Signaling X” in Live Metro Operation
For decades, mainline and metro signaling architectures have been built around trackside equipment. Interlockings, object controllers, and associated electronics were physically distributed along the line—each installed inside dedicated trackside housings. Last month in Singapore, Siemens Mobility demonstrated a major step forward: a live metro train operated using its new centralized signaling architecture, “Signaling X.” Rather […]
