Luckily, the "Stop at" marker was right in front of this obstacle! But what was it doing there -- who made the mistake: the track crew or the vertical girder crew? Ran -- well, nearly-- into this while driving the "Shunter Move" session on the Rhur-Sieg Nord route. Despite this little misadventure, this is a great exercise in maneuvering the BR363. It involves numerous stops, changes of direction, and decisions about how to set switches. just, as I think Rocky and Bullwinkle used to sing, "Look out for that tree!" P.s.: Excuse my loose translation in the title!
