At Last! With TRS2019, my A.I. Trains behave themselves!!

Just ran a 4 hour session in TRS2019, on my infamous Cotton Belt Route, and the A.I. Trains all worked perfectly! Not a cornfield meet, not a train going backwards, not a train missing a "Navigate To", not a single train stopping and refusing to move... NOTHING AMISS!

I am one happy soul here. This has never happened before, not in T:ANE or in TS12. What did you guys do? No, I don't want to know. Whatever you did, leave it alone as far as A.I.'s go. Gosh, Trainz is fun (again)!

(Now if only I could get enough cash to buy a set of tires for my vehicle, I'd be content! )

Brilliant, Dave - well done!
I have zero quibbles with AI in either T:ANE SP3 or TRS2019 beta 96720. Just wish some of my CTDs in TRS2019 would go away so that my sessions last longer.
AI needs to be told exactly what to do - with the right choice of Driver Commands - and to have all the Trackmarks and Nav-points, signalling etc. laid out appropriately.
Then - and only then - it will do as it is told.
Happy that you have managed to achieve this too.
