I have got all inspired and tried my hand at painting and weathering some Hamersley Iron, and Pilbara Rail Dash 9-44CWs
In short, the locomotives were painted silver, and not a hard silver but a reduced hue that is not so punchy.
Then decaled, a word of warning the Pilbara Rail decals are NQR, and I had to fight them into place, took a number of hits to get it right, even now I am not 100% happy.
The frames and walkways were painted a mix close to UP harbour mist grey.
A number of washes were applied, both dirt and rust. The red stripes were painted over with a lighter hue and highlights as per the prototype photos.
A final dusting of chalk and a soot completes the job.
Here are some of the prototype shots, I think I got pretty close.
