Dear Mojang support,

I would like to report a bug that’s about the mechanics of loaded minecarts.

In my world I am running a train consisting of 12 minecarts, as one unit.

They are running at consistent speed on a powered rail track, while I am flying 1000 blocks away.

The issue:

As soon as I reload the chunks, where the minecarts run, I see them still running and have the same distance to each other(regarding the direction of travel), however some minecarts turn out to be misaligned, but still moving at the same speed. Partially the are minecarts, that are up to 1-2 blocks next to the rail.

I believe, that this is not supposed to happen. On the video Minecraft is running with fabric, but I also experimented in Minecraft vanilla without any mods, and the same issue occurred.

What I expected to happen was, that the minecarts should have run normally. All mine carts aligned on the rail track.

How to reproduce:

1. build a rail station like this https://youtu.be/c5YQTi5tZ24?si=gUK_9kt9zi-wg-h1
2. build a rail track (powered rail, but in curves: normal rail)
3. let the train(unit of multiple minecarts) depart from its station
4. immediately fly away, until all chunks in the train area unload
5. unload the chunks again after a time(at least 20 seconds)
6. observe the moving minecarts(as I did in my uploaded video)
