If you encounter a 1000Hz signal, you need to reduce speed. In the HUD this is shown with the 1000Hz light on. After a while, the 100Hz lingt is turned off. You then are allowed to override the imposed speed limit. In te cab this is shown by a blinking speed limit light. In the HUD this is not shown, the light (fi 85 km) is constantly on instead of blinking. This is not correct and confusing if you drive using the HUD.. As far as I know, this happens with all locos. I have seen it in the cab car at Tharandter Rampe (as an example). The image shows the HUD, the 85 indicator should be blinking.
