The system is run by TEC Charleroi, a subsidiary of the Walloon public transport operator (Société Régionale Wallonne du Transport). Intervals between trains depend on the period (weekdays/weekends, holidays, etc.). The standard interval is 30 minutes for lines M1 and M2, ensuring a 15 minutes interval on the common Charleroi - Pétria section. This interval becomes 60 minutes (30 minutes on the common section) on weekends and holidays, and during the July–August period. On line M4, the standard interval is 10 minutes (15 minutes on Sundays and public holidays); similarly, line M3 also runs with 10-minute intervals.
