When exiting a station:

- Automatic blocking section:- One red light: the train is not allowed to pass this signal;- One green light: indicates that there are at least two cleared subsections ahead, allowing the train to enter the section at the prescribed speed;- One yellow light: allows the train to enter the section and be cautious as there is only one cleared subsection ahead;- Two green lights: allows the train to enter the section in a diverging direction;- Semi-automatic blocking section:- One red light: the train is not allowed to pass this signal;- One green light: allows the train to enter the section;- Two green lights: allows the train to enter the section in a diverging direction.
