Erasmus opened on 15 September 2003 as part of the extension to line 1B including the stations La Roue/Het Rad, CERIA/COOVI and Eddy Merckx. In April 2009, this part of line 1B became part of line 5. The station lies at grade and has a single island platform which can be reached through tunnels under the tracks. It was designed by Philippe Samyn and Partners and is named after Erasmus Hospital which it serves.
The entrance is from a street that goes under the station
