Here's the save if anyone wants to take a peek at it I guess I'm going to tear them down and try rebuilding them again but if that doesn't work I honestly don't know what I'm doing wrong. I'm pretty sure I didn't do something stupid and connect them with subway tunnels (can you even do that?).

I really don't have room in my city to make the rails above ground, I want/need the tunnels to work but I can't figure out why they won't. So they DO work, but for some reason NOT when I have them connected by tunnels. I moved my plastics warehouse over to A and the first shipment came by train, as I wanted: Just to be sure I saved, tore a bunch of homes down and built the highest, ugliest railroad bridge connecting the two stations so I could visually see any trains and almost immediately they started using both stations. That is what I thought too, maybe the tunnel is not connected, but I have checked it 4 times, I am 110% sure it should work. It is so massively frustrating to spend so long setting up a very logical and nice system only for the AI to completely ignore it :( I have let the game run for 2 hours to see if the AI will adjust to my stations and they won't even use them once. How do I force them to use my trains? Various old town / ban trucks policies at key intersections did not sway them, they just blow through it because that is the "only way" through by road so they feel they are exempt. I even put a plastic only warehouse set to fill right next to the cargo station at point A, still they want to drive it through all that immense traffic.

They DROVE the plastic all the way across the map instead of using the train. I built a clothing factory at my farms needing crops, animals, and plastic, just to experiment. I have my crop/animal product DLC farm all the way on the right side. I track the trucks and they are going alllllllllllll the way down to the ocean front commercial. You can see more warehouses there and a line of trucks leaving them. I even have a warehouse right next to the station for convenience but they want to drive instead. They just bypass it and choose to use the road. The thought was they will transport materials back and forth and clear up the roads, but nobody uses either. So I built 2 cargo terminals, one at point A, one at point B, connected by tunnels. There is a cluster of industry around point A, and a bunch of commercial near the ocean. I have major traffic issues going from the right side to the left.
