northern portal from driver's perspective ...
 

... and from passenger's view.
 

Entering the southern portal. The distant signal of Bitburg=Erdorf is showing 'Vr1'. Maximum speed of
70 km/h is only allowed from the home signal, as the 'Lf6' signal is showing. The upper border of the photo is dark, but that's not a mistake of the photographer. It is the bridge of the road B50.
