I‘m actually trying to to the journey on RRO. Today I have to drive a 422 from Wuppertal Oberbarmen to Wuppertal Langerfeld Bahnbetriebswerk. I start in Oberbarmen, but after tracks separate, I got a Hp0 at signal R 652, which does not change. If I contact dispatcher, he gives me two white lights and tells o go on slowly. But, here‘s the problem, a few meters on, there is a small signal at the ground, 508, which again shows Hp0. Nothing happens. When I try to contact dispatcher again, nothing happens. So it is not possible to drive on to parking position.
