BloodyPenguin has templates on the workshop to cover these missing ones:
Thank you for posting those links, Avanya.
The template for the Cargo Train Terminal you posted, is good for someone who wants to change the look of the terminal and add your own props/buildings. So I'm sure it will help others.
Unfortunately, they are not exactly what I want. I just want the basic terminal as exactly designed by the developers, so that I can simply adjust the ongoing upkeep expense for the terminal. That's it. Then I can save it as a new asset for my own personal use.
I tried to use Steam Workshop search to find just the standard, basic terminal(s), but saw none.
(I'm not computer savvy enough to know how to accomplish this. If the correct terminal was available in the Asset Editor sub-program within the game, or within Workshop, I know what to do from there, but with it missing completely, I'm lost.)
