Charleroi Metro line 2
Line M2 is a line of the Charleroi Metro in Belgium operated by TEC Charleroi, running from the Monument tram stop in Anderlues to the metro loop around central Charleroi, before heading back to Anderlues. Line M2 was created on  to replace former lines 88 and 89 after completion of the loop around central Charleroi. Introduction of new line numbers (M1, M2, M3 and M4) in February 2012 coincided with the formal association of colors to line numbers. The official color for line M2 is green.

Line M2 is identical to line M1 except that it runs along the downtown loop in a clockwise direction.

Operations
Line M2 has a length of  (including the return portion to Anderlues), of which  are on a standard tram line on the street (in Anderlues) and the remainder on premetro infrastructure. It has 29 premetro stations (18 distinct) and 12 tram stops (6 distinct). Lines M1 and M2 are the longest lines of the Charleroi Metro network.

Trams drive on the right on the entire line, but the regular tram section of the line in Anderlues (outside of premetro infrastructure) runs on the left, right, or in the middle of the street. A couple of portions of that section in Anderlues are single track. 

Because M2 trams going from Sud to Pétria enter Beaux-Arts station from the West and have to leave it to the West, a change of direction is required. Trams accomplish this by first passing through Beaux-Arts on a lateral track without stopping, before entering a loop-shaped tunnel leading back to the station but from the opposite direction.
