!!
I think I found the full version of what seems to be the current version of this mod here (there are a lot of different Hungarian mods so I'm not sure if they just incorporated that one into this one, or if they're very similar, or what exactly is going on):
http://www.szszote.try.hu/Click on "Szszot Mod 6#," (they haven't updated it yet, it's actually version 7) and click on "Szszot mod 7* Letöltése " (Download).
Enjoy!
Remember to turn off the green outlines of the vehicles, otherwise apparently this mod will not work.
Use the boxes (kind of like in the LA mod) outside of the stations to remove the roof, then click on the person inside the building next to another box and make them use it (to open the gates). Finally, use the man at the control desk to page out the vehicles (it's in Hungarian so unfortunately most of you won't understand it - here's an extremely quick crash course for a rough understanding: "baleset" = accident, "lakástűz" = house fire "egyéb" = other).
It's truly amazing, I love it.

Mad props to the makers.
