A suggestion for advanced weathering would be to look at lots of prototype images, and see exactly HOW the locomotives weather in real life.
Things such as: The paint on the roof will fade quickest, and most, as it is exposed to the sun's rays for more hours in the day than either side of the loco.
Diesel soot will be concentrated around, and below the exhaust stack(s), and more so behind them as the soot settles from the locomotive being in forward motion.
The trucks, underframe, and fuel tank (especially the front of the tank) will get covered in a layer of dust from use of the sanders. Also this dust gets sprayed up above the trucks to the lowest parts of the sideframe and running boards.
Sources of heat will fade the paint and decals around them. This is best illustrated on first and second generation EMD's with dynamic brakes. The paint, and decals underneath the DB blisters would discolour from the heat. (this is best illustrated on any CP Rail SD40-2 in their action red paint scheme).
