The public transport system in Brussels, the capital city of Belgium, is operated by the STIB; it is quick, safe, and efficient. Most of the sights in the city center are, however, accessible on foot.
There are four metro lines in Brussels. Line 1A stretches from Roi Baudoin to Herrmann-Debroux, Line 1B from Stockel to Erasmus. Line 2 travels from Simonsis to Clemenceaux. All three connect with the Airport Line, which runs directly between Brussels National at Zaventem and the European Quarter in under 30 minutes.
