metro, Light Rail subway (pre-metro)
The Brussels metro has 59 stations, 4 lines and covers 38.7 km of track It sprouted up in 1976.
There are also 9 tram lines, many of which have been upgraded to light rail. The system includes several tunnel sections, including one in the central city, totaling 12 km. Lines 3 and 4 of the Brussels metro are really light rail lines sharing the central city subway but are sometimes referred to as the Metro.
A new premetro section is under construction, with stations and tunnels fit for the inevitable full metro service. A new full metro line is also scheduled to begin construction in 2012, and plans for automating Lines 1 and 5 have already been approved.
Tram, light rail
The first tram opened in 1876.
In 2013, the Flemish government announced plans to build three interurban tramways totaling 60 km, 15 km of which would be part of the existing infrastructure. The lines are reminiscient of the old Vicinal network which crossed the entire Belgian countryside until it was wisely dismantled in favor of nonpolluting cars and buses.
