Nice shot,but i think its a tad overexposed,iam drawn to the sky in the image because its powerful white colour,adjusting the exposure will reduce this.It seems a tad out of focus aswell but the main thing is the trains a great shot just needs few slight adjustments for next time..

Hope this helps..
