Schuman tunnel
The Schuman tunnel is a 970m long rail tunnel in Brussels.  It passes beneath avenue Clovis, square Ambiorix and the boulevard Charlemagne.  The line running through it is the double track line 161 (Brussels-Namur).  The speed limit in the tunnel is 50 km/h.

The northern portal is under the Chaussée de Louvain station in Saint-Josse-ten-Noode.  The southern end contains the Brussels-Schuman station.  The tunnel passes around the back of the Berlaymont building.  Travelling northwards, the Schuman tunnel is followed by the Deschanel tunnel, then the Schuman-Josaphat tunnel.

The tunnel takes its name from the politician Robert Schuman
