Good morning, I have a problem at every station. When I'm on duty, the bell rings. I've watched tutorials, but nothing works. I don't know how to do this or how it works. Please help, thank.

The "BGF" bell rings, after clicking nothing happens, it happens on various stations, I played on Kędzierzyn-Koźle and Wrocław Główny. I can't send the photo

The bell ringing once every two to three seconds means that a train wants to enter on an single-track route or on the left track. There is a button which is blinking red and white, as well as a train in the "Zugfolge" where the entry is highlighted red. If you press this blinking button and then the button "Akzeptieren" right at the top of the signal box (or F11 on your keyboard when using windows), the train should enter the signal box after a short time.
