Describe the Bug

(English)We build a train of a certain length, and I ride it (let's say here it's a 6-car train, for example).
If I ride in the third car of the train, for example, and create a track long enough to release the actual interdimensional commute and move it in automatic operation, the first or second car will disappear. Is this a specification? Is it like it only loads from where the driver is now to where the player is, for example?

ある程度の長さがある列車を作り、それに私が乗り、(ここは例えば6両編成ということにします。)
列車の3両目などに乗り、実績異次元通勤が解除されるほどの長さの線路を作り自動運転で移動すると、１～２両目が消失してしまいます。これは仕様なのでしょうか？例えば今運転手がいるところからプレイヤーのいるところまでしかロードされないみたいな感じなのですか？

Reproduction Steps

1.I'll make the train first with the Crate mod. 5 cars or more would work well.
2.So they write in the train timetable to go back and forth on the same track. This track should pass through the nether gate.
3.So if you get on the third car from the direction it is currently operating, the train behind it will disappear.
4.Perhaps this disappearance is invisible as an entity. However, there is no hit judgment.

Expected Result

The train disappears.

Additional Context

No response

I'm experiencing a similar bug, I can't confirm that it's a separate issue. I have a debug log uploaded from server side,

The issue that I face specifically is that when a train goes more than a few chunks away to an unloaded chunk, the cars behind the engine will disappear. It could be a few different things from my perspective, entity culling, or some other mod that's improving server side performance. In any case logs are posted below.
