The landscape elements are excellent! And I am a big fan of trains running thru beautiful panoramas, and this is a lovely scene. I agree that the blur belongs, however it's the color values of the train that seem a bit overpowering. 'Greying' out the values would help the train to sit a bit more into the landscape imo. Some weathering and grunge in the textures would be great, but probably not necessary at the distance. All that aside, I really like the image.
