attributed signal, using technology comparable with German PZB. After activation by ATB-Vv the movement of the train is self-controlled with regard to the braking curve. So the chance of a "Stoptonend Sein (STS)-passages" (English: Signals Passed At Danger) is minimal. The system is not fail-safe as a broken beacon will result in the train not braking automatically. ATB-NG Since 1990 a second generation, ATB-NG (ATB Nieuwe Generatie English: ATB New Generation), has been developed to overcome all the problems posed by ATB-EG. The systems is completely different from ATB-EG and operates nearly equal to ETCS Level 1, ATB-EG and ATB-NG can both can safely be installed at the same track as they do not interfere with each other. Trainborne ATB-NG equipment is also able to receive ATB-EG signals, making the system backwards compatible. Because major, electrified routes received priority when installing ATB-EG, ATB-NG is almost exclusively found on diesel-lines as these were the only unprotected routes when the system came out. One exception is the former diesel line between Zwolle and Wierden which was electrified between 2016 and 2017. Operation The system works by conveying movement authorization via balises between the tracks, called beacons, located next to signals and in other strategic places. These beacons are offset towards the left as seen from the driver, making the system directional. The system manages the maximum speed, maximum travel distance, the exit speed and the "release-speed". Speed limits are set in 10 km/h intervals from 0 through 200 km/h and indicated by a yellow LED next to the maximum speed on the speedometer. If the train exceeds the maximum speed by more than 2,5 km/h the LED will start to flash and from 5 km/h above the maximum speed a bell will ring. If the maximum speed is exceeded by 7,5 km/h the emergency brakes will be applied. Braking is managed by a brake-curve relative to the weight of the train. When the train approaches the point where it needs to start braking, the yellow LED will jump to the target speed and a red LED will light up at the former position. The red LED will steadily decrease towards the target speed, ensuring the driver brakes accordingly. If the train speed exceeds the red LED by 7,5 km/h a brake application is induced. When the train reaches the target speed three short bells will sound, informing the driver that he can
