I just rebuilt my locomotive shed and I'm really happy with the result this time.

It's mostly made of strip wood that's been 'distressed' with diluted ink in rubbing alcohol.

All it needs is some soot over the door to look well-used.

I was planning to dry-brush a soot color over the door,
but I thought I'd ask if anyone uses a different method,
since I'll probably only have one shot at getting this right.

Try using a wax candle that puts out some smoke. 

Can use it on tunnel portals too.

Try not to burn anything down.

I lightly air brushed flat black paint in the required areas.

Lightly and many passes with the nozzle to get the finish I wanted,
if I over do the job just wash with the thinning agent (for the paint) and start again.


I aspire to inspire before I expire.

Hi Eric,

I'll second Peter's method.
I had the airbrush adjusted so that it fed more air and less paint.
Again the trick is to sneak up on it with many light passes and a pause to inspect your "smokestains" after each pass.

Here's the effect

Sorry about the focus, but this was cropped from a much larger photo. 

Just found a better photo by Dan  Pickard on his Flickr album of the 2019 Australian Narrow Gauge Convention.

This approach can also be used to stain the rafters and smoke vents in the roof of your loco shed. 
Again blowing more air than paint - aim you airbrush up at the roof from inside the building.
The building will fill up with paint's mist and seep out of the vents, and any cracks in the wall, etc leaving a "smokestain" behind.
PS - don't use a "black" black for the smoke colour but rather a very dark grey.

I use some black chalk ground up, or some of Joel Bragdon's black pigments. 

Start light and increase until the desired intensity is reached.
