I have come across something a bit unusual. On both MSB and RSN, I have seen Hp 2 signals showing "proceed slowly" (Langsamfahrt) with the yellow light above the green one. The first was in Aschaffenburg on the route from the harbour shortly before joining the MSB. The second time was whenentering Hagen yard. Normally, the green light should always be on top of the yellow. Could this be a bug or have the German signalling rules changed?
check the about signaling part link PS I'm just not competent to give you an unambiguous answer! EDIT this one is better > link Or better check this gentleman's signature (information) for some good source \o/
Thank you, I followed the links. Basically, they confirmed my understanding (green is on top of yellow),
