You are right.

The latest official network map published by TEC is from 2021 and the situation has changed completely near the station.

In the current timetable, M3ab departs from bus station B, therefore not here, and heads to Villette and Ouest instead of Tirou.

More than a third of the bus network in Charleroi is presumed to be incorrect or outdated; this is something we are trying to patiently fix, day by day.
