Weathing locomotives projects Ho scale

Hi everyone I have a new skill now which is weathering a piece of rolling stock, building, locomotives you name it I'm getting better applying these powders and pastels as well. the only thing I'm not good at is the air brushing that I still need to work on. but I now have 3 locomotives weathered now 2 FP45s freight bonnets and 1 F45 freight bonnet as well. I will be sure to make a video on these soon.
