This bus is from CATA in Lansing Michigan.
This is a new skin texture.
If you want new loading screens to go with the RTS, go to "Misc" and click on "HUDs, Maps & Menus".
i'm sorry, i'm not a modder, i only did the skin. Schaefft, he is the modder who made the bus, see if he will, and tell him that i would like the Flxible Metro too, that is my favorite bus.
