Wow, that Coaster reskin is pretty dang spot on (ignoring the 315 near the rear, of course)!
Except instead of black at the base (plow, fuel tank, etc.), it should be a lighter gray, and "COASTER" on the sides should be a bit bigger and moved so that the C and O (E and R on the other side) are where the 315 is. Other than that, it's the most accurate Trainz model in Coaster colors I've seen so far.
