Reproduction Steps

not exactly sure, but i remember just approaching a train station(pressing space) in the nether while i was in the overworld

Additional Context

(badly) formatted extracted carriage contraption entity nbt(located in the nether): snbt.txt

even though the dimension the entity loads from is the nether, it might be in an overworld region file

as i previously suspected, the contraption entity might not be stored in an entities folder region file at all

its either in other region files or a separate file(very unlikely)

the latter indeed was, at least the crash is present when create_tracks.dat is in its data folder of the world

stored in [root tag]/data/Trains[0]/Carriages[0]/Entity(in the create_tracks.dat file)

manually edited in valid values based on valid train data as temp fix

temp fix worked

time to attempt reproducing on the original server

so far no luck; will reopen when this issue occurs again

note: the carriage itself did arrive into the nether properly respecting position of track(halfway to the station) but something corrupted the main entity coords upon loading.
position is equal to position anchor coords in EntityPositioning tag which is stored on the same level as the Entity tag, figured out relative AABB values by building a carriage of same size dimensions in another world, rotation values fixed themselves.

I have also just had this issue, station was before portal into the nether. Don't recall if i was accentually pressing the 'goto station' button causing the crash. Position of train became NaN and I wasn't able to join until I removed the corrupted train from create_tracks.nbt using NBTExplorer.
