This line was created on 14 March 2011, replacing tram routes 23 and 24. Routes 23 and 24 followed the same trajectory between Vanderkindere and Princesse Elisabeth/Prinses Elizabeth, where route 23 deviated towards Schaarbeek railway station, one stop further. Together with tram routes 3, 4, 8 and 9, it is one of five 'chrono' lines, which means that it is served by low-floor high-capacity trams with a high frequency. The low line number chosen for the new line shows that it is either a metro line or a 'chrono' line.
