Hey there! I wrote this theard because, as a real french train driver, some things ... are note ok . First of all: KVB, the « 00 » NEVER should come out on a green signal. It's only come out on a yellow signal. This "00" mean KVB will control the speed at 30km/h at 200m of the annonced signal. Only in this situation. "F signal" are not on the red state by default. In BAL (block automatique lumineux) signals use the track circuit. This mean the state of the signal change if there is a train ahead or not. So by default, "F signals are on the green state. "Nf" signal are good they should prensent 2 red light by default All signals are "F signals" on this exemple Power switch signalisation In the power switch, it miss one signal. Missing the 1st signal I hope you will see this theard! Sorry for my english, i'm bad at it...
