Ruhr-sieg Nord, Surprise Red Signals?

Hey everyone,

I'm finally getting to Ruhr-Sieg Nord, and I'm getting caught off guard by all the last-minute surprise red signals.

Am I doing something wrong? Should I activate PZB?

EDIT: FIXED; It was an issue with the signals, all explained in the manual. https://steamcdn-a.akamaihd.net/ste...eg_Nord_Driver's_Manual_-_EN.pdf?t=1534338379
