Soooo, what are your techniques ?

Well,I suppose I'd better start the bidding.

I have only weathered a few of my loco's so I'm not really qualified enough to give any kind of tutorial.

What I use is the Modelmates weathering liquids and Tamiya weathering powders as well as some of the bagged up powders.

I paint on the Modelmates liquids onto the model then let it dry.After it is dry I then use a wettened cotton bud to remove the excess weathering dye.This is an acrylic liquid so there is no need to use thinners,just water.I go from top to bottom with the cotton bud so this gives the impression of rain washing away some of the dirt.After this has been done to my satisfaction I turn to.the Tamiya powders.These are on a tray that looks kind of like make up.I use a cut down artists brush so it is a bit stiffer to stipple on the frame dirt coloured powder so that it looks like filth thrown up the bodysides.Next is the roof dirt.I use tha Tamiya stuff once more and just stipple stuff on aroud the exhaust ports,heating boiler exhausts,cooling fans and grilles and finally the soot around the exhausts.His is done with the bagged powder or charcoal scraped against a scalpel blade.

Once I'm satisfied,it gets a very ligh spraying of lacquer,the dull kind or nonscented hairspray.

Of course there are some on here with airbrushes but as it would go unused for 99% of the time,I have decided not to buy one.

Yet!

I quite like weathering powders and a little dry brushing. I've also sometimes painted under-frames and bogies with 'Frames dirt' colour.

I'd recommend getting and reading some books; 'The Art of Weathering' by Martyn Welch, 'Done in a Day' by Pelle Soeburg and 'Weathering locomotives' by Tim Shackleton.

There is a nice little article in the Latest N Gauge Society Magazine.
I favour diluted acrylic paints that can be dry brushed to carrying degrees.
