@aetios@Erpel in poland you would have yellow, here instead you get green + double yellow, the top one with green lighted is the current signal, and the one with double yellow is for next signal and iirc green+yellow there means you have to slow down on next signal and double yellow means you have to stop before next signal
@aetios@Erpel this is like the most "complicated" polish setup outside of stations and its still less of a mess than the german one (all of that is on www.transportszynowy.pl/Kolej/sygnalizacjaswietlne) S1 (red) - stop S2 (green) - proceed with vmax S3 (blinking green) - slow down to 100km/h before next signal S5 (yellow) - proceed with speed of 100km/h, next signal is stop
