Rhein-Ruhr Osten heading away from Wuppertal for Hagen Yard, a few minutes into the trip this yellow device showed up as a red signal, had to contact signaller to progress which was allowed. I assume it's either incorrectly regarded as a signal or the signal it's self is missing, hopefully from the screenshot you can see where abouts on the route I mean.....
Is it right. The signal is located to the left of the track. There is also an additional arrow on it, which indicates to which track the signal belongs.
Just to add (I have discovered via Google/Wikipedia) the meaning of the signal is exactly to stop and await permission to proceed (and the yellow box is part of the axle counter/train detection system)
