Specific Path for TaskExecuters

I'm a beginner here so please forgive me for stupid questions. I'm trying to create a subway line with two TaskExecuters. Each stop has a queue where the passengers are picked up and a sink where they are dropped off. Do I need a Dispatcher to control both TEs? Also, on my model (which I attached) the TEs go in different directions at NN4 but then both are supposed to reverse direction once they hit the end and come back along the same path at NN4. Do I have the network nodes setup right? Any help would be appreciated.

I've got both TEs moving but they are not hitting all the nodes I want them to. I also want them to follow the identical path until the split off towards the end. This would mean a 30 second delay for the 2nd TE

I think you didn´t point out clear enough what you are trying to do.
If I look into your model, I see that you did´t turn off the offset travel for load and unload tasks. Is this right?
I even would built a network which only let the trains run in one direction. But I´m quite sure that I didn´t completely understand what you are trying to do.

Thank you for responding. I've adjust my model and attached it here. I want it to stop at each queue and pick up the max amount of people it can hold, which is 15. Drop off a random amount of people at the next sink and then move on to the next queue and fill up to 15 again and then drop off a random number of people at the next sink. This repeats all the way through and then after it comes to the last sink I want it to go in reverse along the same path.

I think what you are really looking for are "TASKSEQUENCES". Your model works as well as possible without creating your own tasksequences. You could extend it with the pickoption: "Unload all items intended for this station before unloading to other stations " in the onLoad / onUnload Trigger of TE. But this will not solve the problem that you want the TE travel from one to the next station, stop there, unload and load "items" and so on.

Just had a similar task some years ago, maybe this thread can give you the first direction:
