Installation

Extract the z___BSC MODs parent folder into your Plugins". 
It's gonna install the following paths additional subfolders at the end:

• Z___BSC MODs/VDK Automata/VDK Train Mods

• From the "Freight Engines Rep (CHOOSE ONLY ONE)" folder, pick only one DAT (VDK Train Vol### FE Rep [...].dat - This is the main train mod for freight engines) file. This download will not work with any other Freight Engine Train mods installed! Make sure that this mod is loaded after the Network Addon Mod (the provided z___BSC MODs folder will actually ensure this), otherwise the new UDI icons won't show up.  You may only use one option for freight replacement mods. All others will need to be of the additional type "Secondary Engine Mod (Addon)".
• From the "Steam Engines Rep (CHOOSE ONLY ONE)" folder, pick only one DAT (VDK Train Vol### SE Rep [...].dat - This is the main train mod for steam engines) file. This download will not work with any other Steam Engine Train mods installed! Make sure that this mod is loaded after the Network Addon Mod (the provided z___BSC MODs folder will actually ensure this), otherwise the new UDI icons won't show up.  You may only use one option for steam replacement mods. All others will need to be of the additional type "Secondary Engine Mod (Addon)".
• From the "Secondary Engine Mod (Addon)" folder choose any and more or all DAT (VDK Train Vol### FE Add [...].dat) file for adding additional trains to your rail  network.

Due to first the Project ZIP efforts, then the SC4D LEX Restoration efforts in order to make the folder structure more unified the original install location (VDK Automatas BSC) and the file names have been changed.
To avoid conflicts, please, it is highly recommended to use any of the third party cleanitol tools and remove any previous versions from your plugins. In the ~Documents folder in the main ZIP you can find a Cleanitol_BSC VDK Train Mods[...].txt file and by using either the newer nos.17's SC4 Cleanitol or the older BSC Cleanitol tool you can search and remove old and outdated versions of these files. 

The letters on the pictures above, helps you to pick the file you want to install. There are 3 different kinds of mods:

The FE Add mods in this packages can be used with any of my other FE Add mods, like the engines from Vol17.

The trains mods need to be loaded after the Network Addon Modd.

Uninstallation:

For uninstalling the files, simply delete the files from the plugins folder.

Known problems:

When using custom automata mods the game will occasionally show "ghost trains" just after loading (trains showing up just outlined, or only partly visible).
This is normal, and nothing to worry about. Noticed this is showing more, the more train mods you have installed. Then its not just after loading the game.
