If trains are completely separated from pedestrians or any other form of transportation, then 100% automation was possible a century ago. As soon as they’re not, the problem becomes much, much harder, and is not fully solved yet.
Trains take so long to stop that having a human in charge isn’t going to do any good in terms of avoiding pedestrians or any other form of transportation.
However, since you only need one person driving a train that can carry hundreds of passengers it doesn’t really make sense to replace them with AI. The small savings of having one less salary to pay is offset by the fact that you no longer have someone to blame when things go wrong.
