Last time I visited the Belgian/Gernam border area I spent quite a lot of time investigating the Vennbahn but I failed to stop at Roetgen Station. The borders around here are particularly confusing so on this trip I took the opportunity to wander around a bit and record some video of the area.
The station is just north of Mühlenstraße on the map below (reproduced from the blog of my previous visit)
The exact border lines on the road are not clear at all but some of the signs on the buildings give some idea of where they might lie.
