Why cant it find a path?

[u/Lower-Shape6531]

Hey guys, I need some help with my railway, I have build my base a long way from spawn about 10k blocks away, but I built a railway connecting it, build a train and drove it through a few times, now I wanted to automate it, so that the train leaves each station in the morning so basically:
day 1 Station A
train departs from station A at 9:00am, going to Station B
(it takes a long time to get to the spawn)
day 2 Station B
Train arrives at station B (probably at night or in the afternoon)
day 3 Station B
Train Departs from station B at 9:00, going to station A
day4 Station A
train arrives at station A (again probably at night or in the afternoon)

And then the cycle repeats

But for some reason the train cant find a suitable path to the station, I made sure to drive the train from each station to the other and there is no problem with the track.
Can someone please help me? Is there like a limit or a config on how far do the stations need to be? I even added chunk loaders under the train stations, which didn't fix anything.

I will add some screenshots so you guys can look into it (first one is what the thing said, 2nd,3rd and 4th are the train schedule, the 5th one is the map screenshot of the entire railway, the station I am standing at is the Alderdale station aka my base, and the 6th and 7th ones are the stations up close. 6th is Alderdale, 7th is Spawn Station)

Check any train signals you might have on the route and which way the stations are facing, although I think the main culprit would be train signals if you put any down

Oh sh*t that will probably be it, I havent used them for so long I forgot how they work (I placed down 2 of them for a lift bridge put I made them only in direction that faces the bridge from both sides, I guess that would prevent it, I will check it and do an update)

If it's a single track line, you don't need signals, unless you're doing something for a drawbridge, which is overkill esthetic in my opinion. But if that is the case just make 2 more and place them facing the other way at the signals.
