PZB Assist is a focused Android companion for railway enthusiasts, train simulator drivers, and anyone who wants to better understand the German PZB 90 train protection system.
Instead of relying on tables and memorized numbers alone, PZB Assist presents key PZB supervision limits in a clear, visual format. The app covers normal 1000 Hz and 500 Hz supervision and supports the standard O, M, and U train modes, making it easier to understand how monitored speeds and supervision curves differ depending on the selected mode.
Clear graphs help visualize how PZB supervision develops after passing an active magnet, while color-coded information and an easy-to-read interface keep the most important limits accessible at a glance. A built-in practical guide provides additional context when learning the system or refreshing your knowledge before a simulated drive.
PZB Assist also includes sound and haptic feedback, helping create a more intuitive and engaging learning experience. Its multilingual interface makes the app accessible to railway enthusiasts and simulator users around the world.
