BVG tests system for more accurate displays at U-Bahn stations - Berlin's U-Bahn tests real-time radio tech to fix unreliable train arrivals

Berlin's U-Bahn network is testing a new radio system to track trains in real time. The technology promises to replace the often unreliable 'BVG minute' displays with far more precise arrival times. Initial trials have already started on the U2 line.

BVG and tech firm MOXZ are rolling out what they call a 'globally innovative' radio solution. The system uses custom-built devices on trains and in stations to pinpoint location, speed, and arrival times—down to the metre—even in tunnels.

Tests began in February 2026, with plans to install a full tunnel radio network in the coming months. The goal is to give control centres second-by-second updates and make platform displays far more accurate.

Henrik Falk, BVG's CEO, described the project as a 'smart innovation' that will improve operations for both staff and passengers.

The pilot focuses on the U2 line, though the exact duration of testing remains unclear. If successful, the system could end the long-standing frustration with vague arrival estimates. Passengers would then see exact train positions and timings on displays.
