A Talent train is coming from Euskirchen and is going to Bonn. Here it comes from Witterschlick and the next station is Bonn Duisdorf. The signal is a so called Vorsignal. Roughly translated "Fore Signal". When the disc is in the horizontal position, the Engineer knows, that the next main signal lets him pass and he needn´t slow down. The arrow below the disc is another chapter. I´ve filmed it during moving on another place of this line and I´ll explain it there.
