Continuing with building up (and decreasing, in the case of the 08) weathering effects, here are some more progress photos, taken on the layout near Newton Broadway station.

In the case of the O2 I also 'doctored' two of the photos to resemble older images in black and white and sepia tones. They then give me some comparisons with the photos I am working from in various publications.

The 08 shunter has had a partial wash and partial dry-brush effect with grey, Humbrol #66 (called olive drab). I had to use a cotton bud and turps to feather the edges over the top corners of the bonnets. I also used a few dry-brushed strokes of rusty brown along the lower edges of the frames and brake blocks and rodding.

And to the O2, with a lot of grey (#66 again) washed and dry-brushed over most of the areas below the footplate, plus the running board top surfaces and smokebox.

And the black and white versions of two of these:

And the sepia tones. I think these look particularly effective, myself.

As before, these are still works in progress, but I am happy with the way they are going, at present.
