This is really off topic, but I'm really curious. What is the meaning of these signs with the blue diamonds? I've seen them now and again on German routes and hope someone knows what they are. These two are in the freight yard at Hagen. Thanks!
In Poland, the same indicator has the following description: Indicator We4 - means that the entry of electric traction vehicles is prohibited to the track where the indicator is located Who knows...
In Germany it is called El6 and means "Stop for trains with raised pantograph" - which basically means the same as in Poland, don't go beyond the sign with your electric loco
