Ian hi,
I do not want to discourage you but honestly it looks more like painted rather than weathered.
Some advice; practice/experiment your weathering on cheapish boxcars first. Always have a photo of the prototype in front of you. Examine it very carefully. Airbrushing is a method but try water based acrylics first, using soft brushes, try to dull the shinny plastic of the loco/carriage. Use weathering powders for the last touch. And most of all be patient. At the end you will notice the progress you have made.
For fine examples of weathering check out:

Once you get the grip of it, you'll be an addict of weathering.
Best of luck
