Hi. Just had a lot of difficulty with Ruhr - Sieg Nord DB80302. Its a freight service that follows a passenger service but there are no (except for one) yellows. Just green then red. Even if given 1km notice, very hard to slow train without completely stopping. Ended up running a red when given 500m notice of red.
Yellow isn't part of Hv Signalling. Only main signals (Hp) are shown on hud, Distant Signal like expect stop (Vr0) are only in gameworld. Ks Signalling have yellow but it is used only before Finnentrop. Keep your speed lower (60-70kmph) if line is busy ahead of you. Brakes are little buged on RSN and even minimal setting is very strong.
