Hi Tonny,
I have 2019 European version here and sofar no change in the working of signals, since the original, SP1 or SP2
can you be more specific?
-What route you noticed problems?
-What signals are used on that route? kuids
-What exactly does not work? behaviour in game or lights or script behaviour?
Here all Dutch signal sets work fine in my route.
I downloaded UMR2021 a Canadian route and signals work fine there to
greetings GM
