The premetro and tram route 4 in Brussels, Belgium, is a tram route operated by STIB/MIVB, which connects the Stalle Parking stop in the southern municipality of Uccle to Brussels-North railway station in the municipality of Schaerbeek.^[1] It was created on 2 July 2007 as a new route between Esplanade and Stalle Parking. On 31 August 2009, the route was shortened with a new terminus at Brussels-North, while line 3 was expanded between Brussels-North and Esplanade. The colour of the signage for this line is pink.

Only tram lines 3 and 4 remain in the North–South Axis that runs underneath the Pentagon (Brussels' city centre) during the daytime. In the evening, the North–South Axis is serviced by tram route 32. Both lines 3 and 4 have a 6-minute schedule during rush hour and are serviced by the modern low-floor trams (Bombardier T3000 and T4000).

The line was created on 2 July 2007, replacing tram route 52 between Esplanade and Brussels-North railway station and tram route 91 between Stalle Parking and Vanderkindere. Together with tram routes 3, 7, 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.

From 31 August 2009, lines 3 and 4 changed their northern termini. Line 4 was shortened to terminate at Brussels-North, with the route between Brussels-North and Esplanade operated by line 3. Because of this, the very long line 4 and the short line 3 are now equalised.^[2]

Originally, the shorter line 4 did not run after 8 p.m. because tram route 33 had been extended to Stalle Parking. From September 2011, route 33 was suspended, replaced between Brussels-North and Bordet railway station by an extension of tram route 32 from Brussels-North to Da Vinci. At this time, evening running of line 4 was restored.

The route crosses the North–South Axis from Brussels-North to Albert. The tunnel crosses the municipalities of Schaerbeek, Saint-Josse-ten-Noode, City of Brussels, Anderlecht, Saint-Gilles and Forest. It then rides along the Avenue Albert/Albertlaan, which is a part of the Greater Ring, up to the Vanderkindere crossroad in Uccle. There, the route uses the Avenue Brugmann/Brugmannlaan, which then becomes the Rue de Stalle/Stallestraat. At the end of that street lies the tram terminus next to Stalle Parking.
