The uppermost track is a rather steep incline from Bruxelles (Midi) to the right uphill to the left. At the fork, bearing right, the track goes to Echternach (Lux) where it loops back. Bearing to the left the grade gets even steeper with after a branch-off going to the Echternach Coaling Station, the track forks again, ending at the Stuttgart Industrial Park or connecting to the Dettingen-Stuttgart Main Line. The section above the Esternach branch is only open to Freight traffic and Heavy Haul engines (DB E94).
