[Mod] Advanced Trains [advtrains] [2.9.0]

[nazgurth]

Two turnouts in my world are randomly turning back into normal tracks every time I close Luanti.

....

Edit 3: downgrading advtrains to 2.8.3 fixed the problems. I think upgrading to 2.9.0 made closing Luanti just reset everything to however it was before the update.

Please check your debug.txt for messages. It sounds like the nodedb is failing to be updated. When Advtrains reloads an area, it will reload from the nodedb.

Yes, I can see

2026-04-01 15:09:14: ACTION[ServerStop]: [advtrains]Restore node database: Replaced 0 nodes, removed 0 ghost nodes. (took 33ms)

after the times I closed the world with 2.9.0 instead of

2026-04-01 21:58:58: ACTION[ServerStop]: [advtrains]Saved advtrains save files, took 23 ms

along with a bunch of the same restore messages in random other places.

Maybe the following information has something to do with it?

No, and these files (with the tilde at the end) do not appear to be in the repo to begin with.

No, and these files (with the tilde at the end) do not appear to be in the repo to begin with.

Whatever they were, they exist in the 2.9.0 advtrains_interlocking, advtrains_line_automation and advtrains_luaautomation locale folders, but not the 2.8.3 ones. Their file type is "Backup file" and MIME type is "application/x-trash". The icons look like holographic/ghost text file icons.

Interesting. It seems like these files are not present in the repo but packaged into CDB. I suppose there was a packaging issue here.

In any case, the .po~ files are backups of translation files; they do not have anything to do with server-side track placement logic.

Note to orwell: please consider using git archive when packaging.

I downloaded the .ZIP of all (https://gitea.your-land.de/Slightly/sc_ ... ain/tracks) and put it in my mods, but if i select it this fail is comming. (I have this time version 5.9)

The mod is here https://gitea.your-land.de/Slightly/sc_ ... ns_patches. New UI for wagon properties coming today.

Ok. Thanks! Today are holidays again and i can play mt again 🤤

(Minetest 5.9.0 Singleplayer)

I placed a train (Train ID: 129310) with Line and Routingcode "U1", placed a timetable and created a new line:

Line: "U1",
Variant: nil,
Dest. Display: nil,
Disabled: false,
Contiues: nil,
Stations:{
0:{
St. Time: 1,
Station Code: "SpawnHBF",
Mode: "Normal",
Track: "TestA",
Position: nil
},
0:{
St. Time: 1,
Station Code: "SpawnHBF",
Mode: "Terminus",
Track: "TestB",
Position: nil
}
}

I activated ATC and the train drived from "TestA" to "TestB", but in the timetable its "U1 Spawn Hauptbahnhof unknow state". Why it don't print the train? (in command /list_trains and /list_trains+ aren't trains with line and the train have Line "U1" like the line from Line Editor). Can you help me please?

Or is the probleme because of the stop position?

Hm, these are the backup files that msgmerge (from the update_translations script) leaves behind, i forgot to clean them. But I don't think they cause the issues you see.

It looks to me like it fails to save the save files. then next time it starts up again it restores the last known state. because advtrains also keeps a storage of all tracks in the world (the nodedb) it also restores these.

It's curious that it works in 2.8.3, because there were no changes at all to the save format and/or the saving code. Are there any error messages in the 2.9.0 related to saving? I take it the "Saved advtrains save files, took 23ms" line does NOT appear in 2.9.0?

It's hard to tell without screenshots. but two things that you could check:
- the station code in the timetable needs to match the station code of the station/stop rails along the route. in your case the station code is "SpawnHBF" but supposedly the stations are "TestA" and "TestB"? this doesn't look quite right.
- the starting station needs to be set to "Begin timetable" in the departure mode. If you set it up correctly then your timetable will appear in the dropdown there.

It does not, yes. I can't see any error messages, the only saving-related thing I found was loading the save files.

Hi nazgurth,

Thanks for pointing this out. I confirmed that I made a stupid mistake when exporting the mod for ContentDB, and left the NO_SAVE mode enabled. TODO for myself: enhance the release script to confirm that there are no uncommitted changes.

I updated the zip on the contentdb. Please try to re-download.

Today are holidays again. And i couldn't load up a screenshoot. I don't know why... But I will try again...
More datas are comming later with a edit.

Updated: YES!!! After trying do it (I set Begin Timetable [Interval: 60 ; Offset: 30] and more) it print "'U1 Spawn Wendeschleife' in operation". Thanks!

[NicoKaiserHello]

But how can i stop the train at "on request"-stations? I saved now the one as "on request"-station and it prints "Next Station: Spawn Wendeschleife (on request)" ("Wendeschleife"="Turn"). But the train is driving slower and then he drive away from station... Is there a button system or a sensor for the platform?
