4 track mainline test route

I'm considering making a simple test route that has a long mainline that goes from 2 tracks, to 3 tracks, and then to 4 tracks, then back to 3 tracks, then back to 2
This is to show off AI trains operating on 4 track stretches and how they often go in both directions on all 4 tracks
examples:

4 track section:

a train on track 2 westbound, waiting for 2 eastbounds, 1 on track 1, and 1 merging from track 2 to track 1
a train on 1st track westbound, diverging all the way to track 4
2 tracks eastbound on tracks 1 and 2, the one on track 2 stops to wait for the one on track 1 to overtake it as a westbound on track 2 is waiting on the same track, then the track 2 eastbound leaves onto track 1, then the track 2 westbound leaves.

3 track section:

train on track 2 eastbound stops at the end of the 3 track section and waits for 2 westbounds, then proceeds to track 1
train on track 3 merges to track 2 to be overtaken by a high-priority train

2 track section:
2 eastbounds racing and since there's a opposing train on 1 track, 1 stops to wait for the other to overtake before crossing over to that track and then letting the other through

are these accurate operating styles? Maybe on Powder River?

i'm pretty sure there's something on the DLS showcasing such an operation?
