There are so many mods for Transport Fever! By this point we're convinced that more than a few of you have assembled impressive fleets of your own that far overcome the standard builds by way of mods. Why not live in a world where you have just your modded acquisitions to choose from without those silly vanilla options? With this mod you can. It disables all vanilla transport making only your modded vehicles and equipment available for use.
