Anyway, let me know if you want it (it's a UK loco remember, not a US one, so
just that fact might cause some confusion among the viewers) and if so, what

I could make something suitable, given the drawings, but it would take a lot
of time and effort. The best bet might be to buy the models if no free ones
can be found - I'll have a bit of a dig around, see what I can find and get

You might want to set the interpolation time to be relative to the aircraft
speed, to simulate the effect changing over distance instead of time.

Re-applying the weather settings would then just randomly select one of the
