Welcome!

@scorpanelo:
I understand that you have created a separate add-on, BUT in order to use the functions of a train, you need an original SW addon as a base addon. It must be based on an original SW Addon to function properly. That's why the SW Base is denying it.

And you addon seems to be a copy / clone, otherwise the SW Base would throw no error.

I sended a friend request.

@SligWolf if you want, you can send me friend request and take a look at addon

@SligWolf it's already on workshop but available only for friends cuz i need provide some small changes

@SligWolf i mean SW Diesel Ludmilla used only as example, the only thing was taken it's lua scripts, but they was changed a bit to my purpose but everything else fully custom made by me.

you need to understand that this is not rework or addon to SW Diesel Ludmilla this is completely separate new electric locomotive which was made by me

and i have one problem with publishing. when i try in /addons my mod it's work fine but when i upload it and download it via workshop sw base says "Unapproved or conflicting addon detected. Please uninstall this addon:"

@scorpanelo:
I'm also interested what you made, you could upload your addon to your WorkShop so I can take a look at it.

@scorpanelo:
No that's not possible.
The whitelist you mean is only for official SW addons.

If you use the SW Diesel Ludmilla as a fork addon, then you should programm your functions based on the original.

Means:
The original addon must be subscribed, so your addon can work properly. That's at the moment the only way you can do it if you want to use out base addon.
