Diabolo project

This would make Brussels National Airport a fully-fledged international railway station on the model of Amsterdam's Schiphol or Paris' Charles de Gaulle.

Before the project, the airport had another station, a terminus, linked only to the Brussels-Leuven line with a single track and only connecting to/from Brussels.

The connection from the airport station to the new line was built by SA Diabolo in a Public Private Partnership.

The 25N line was built by Infrabel along the exceptionally broad (40m) central reservation of the A1/E19 motorway from Schaerbeek/Schaarbeek to the new Mechelen station.

To fund the project and the operation of the line, a surcharge (currently €6.90) is charged on most train tickets to and from Brussels Airport station.
