Weathering Techniques for Model Trains

By Ryan Kunkle

Updated 06/13/18

Real trains spend years out in the elements and many show the signs of this long and hard service life. Weathering can take many forms; rust, grime, patched and peeling paint, faded letters. There are almost as many ways to recreate the ravages of time and nature. Weathering a pristine model can be intimidating, but it is not impossible. With practice, you'll be adding years to your roster in no time.

The techniques described here can be used individually or combined to create an endless...MORE variety of weathering patterns. They will work on models in any scale and made of different materials.

It's always a good idea to practice new techniques on an old model or a scrap of plastic or wood prior to starting your first serious model. Good reference photographs of the prototype, whether it is the specific rail car or just the general look you're trying to capture, are the best tools to help your weathering achieve a realistic appearance.
