uh, no (:-)).  the rails ought to remain "shiny" I think, and wear perhaps show
on part of the wheel shoulders; the "rust" is excellent in parts.  and, because
everyone's a critic, I'll point out that sleepers (the ones I know) aren't near
square, more like 2:1 width to height.


regards, jr.

Well, the interesting thing is that the photograph Bald Eagle referred 
to earlier, shows this kind of (micro) normals. I certainly overdid the 
effect here ;-) more subbtle effect might be better...

Concerning the sleepers: perspective effect! ;-) They are rectangular in 
cross-section.

Agreed. I have difficulty to get the right shade here within the isowood 
facility. Up to now, my attempts were not convincing enough. I shall 
continue tweaking.

Start with a dark brown base. ALL the sleepers that I ever saw where 
dark brown to black.
With isowood, you can use a plain unpatterned pigment.

perspective, huh?  :-)  (still think they look quite tall)

would that be more noticeable where there would be less mechanical wear?

An image telling more than any text... [attached image]

Where would that be? the whole (?) polished part of the track is subject 
to mechanical wear...

In any case, this is not so important imo. Hyperrealism is not my goal 
(never was). ;-)

I guess I am about done concerning sleepers, rail tracks, and trolley 
textures. Here a view of those changes.

Specially for jr ;-)

The sleeper at the origin is Friedrich Lohmueller's original CSG version 
as comparison. The others are isowood versions.

thank you.  fwiw, if the centre one's colour had a smidgen more "creosote"..

from the mannequin's POV, along the top-outside-corner of each rail, that is,
I'd expect most wear on the inner "edges" due to the wheel shape.

damn.  I was about to suggest the cab should be in "British Racing Green" with
gold trim ;-).

It's an interesting thing, those train wheels:
