Hi, i'm trying ur mod that seems very interesting. About loaders, I try many mods that adds loaders but there's only one mod that enable them to load the train:

And will be nice have only one type of loaders in a mod pack. Could u add an option to enable ur loader to load the vagon too?

Hello, working with trains is very stressful to the system and bad for UPS/FPS. There is only one mod that doesn't negative effect on system - this is Miniloader mod.
If you want loaders to work with trains, then I advise you this mod. Especially for this, I made it possible to disable loaders from Krastorio in the mod settings menu. Disabling loaders will not negative effect the system and will not break save files.

Could i use ur spirtes to make a skin for miniloader?

Of course

@ Linver im using the Miniloader. They are mostly Upsfriendly.
IF u want to use the Krastorio Loader u can just fill the Chests and get a Mod for bigger Stacks for inserters.
so u can also use a fast way to handle / fill the trains.
