I could use some help learning how to properly weather rolling stock, I've done some boxcars that look ok, but I feel like I'm lacking in that aspect of things.
I might be able to give ya some advice there...
My personal favourite way to weather is pretty simple. I'm using GIMP, but it can be easily applied to most other programs I believe.
On a separate layer from the loco, choose the Airbrush Tool. As well, choose a colour (or multiple) to best represent the weathering you want - for instance, coal-weathering warrants black, dirt/mud is some browns, etc. I set the Opacity of the airbrush tool down to ~10 or ~20, or between. Then you just spray it around the locomotive wherever you best want it.
Few other pointers:
-For better results, use different Brush types - I use the Chalk 01 & 02 brushes in Gimp usually
-Use multiple colours where applicable (typically dirt/mud and related)
-Use different opacities and brush over where you've already been to get a heavier weathered look to it. It deepens the colour often and works for some of those areas that get more dirt than the rest.
-Back on your main loco/rollingstock layer (or layers of texts and designs), chip away at some designs a bit with the background colour and sort of break up/cover up some specific things. Example below.
-Use rust/weathering decals! I strongly recommend these, as they can totally change the look of a locomotive. I made a rustbucket using a bunch of these from Textures.com.

Using the decals is simple - bring it onto it's own layer (drag'n'dropping it will typically just do that for you), set the Layer to 'Multiply' - this will allow you to still keep the detailing on the loco/rollingstock - and simply align it where you want it.
Like I mentioned before, I heavily rusted up a locomotive using the decals and some of the standard weathering:
You'll notice the 'Silver Lines Railroad' text and the black stripes were beat up by chipping away at them with the grey used for the rest of the loco (gotta love the Clone & Heal tools haha).
This can all be applied to rollingstock and scenery objects, too. For instance,
The Milwaukee Road (MILZ) trailer closest to the camera got a pretty light weathering just using the airbrush tool with some Chalk brushes.
This is all just the way I've learned to do it, and there are probably better ways to do most of it, haha. But I've been using this for something like over a year now and it has yet to fail me. If ya have any questions, feel free to ask. Weathering can be a nice and simple thing when you get it down.
Cheers,
