The station was opened in 1958 in the old airport building, mainly for the universal exposition in Brussels. With the opening of a new airport terminal in 1994, the railway station was moved in 1998 to a new location inside the new building. Following the completion of the new Diabolo project, the station was extended in June 2012 to enhance the comfort and passengers experience. The trains arrive and leave from level -2, with ticket desks on level -1. Passengers can go to the different floors in the airport and railway station by using a set of escalators and elevators, a couple of meters away of the platforms.
