advice on styrene wraps to add rivet detail

[doctorwayne]

I like the look of coal boards, too, and they do add some detail to the tender.

Here's an Athearn USRA tender with coal boards added:

This is the Bachmann version of the USRA tender, the same as yours:

And another Athearn tender:

The CNR loco has actual boards (styrene), while the other two tenders shown have extensions of the coal bunker - increased capacity either way, but a slightly different appearance.

I don't recall the window sash on NYC locos being anything other than black. As you know, the CNR used red, which I also used on some of my locos:

If you want just a touch of colour, dark green can be pretty subtle (so subtle here that it's almost not noticeable)
