Good crop of entries this week, difficult to see who would win out, to answer Royal Male's detailed post about what was done to the image, use of dodge/burn and the selectively brightened side of the train are the kinds of things not permitted as a very select few have access to these tools and/or the knowledge to use them. As for the selective sharpening you did, that must have been a high setting to make so much noise.
Whilst the shot stood out well, it was still the fact that the platform on the right seems so bright and sunny, yet the unit on the left is almost pitch black, which put me off.
Having recently been to the Severn Valley in dull conditions and finding monochrome/duotone images far more appealing than the original colour images, I'd love to see the colour out of camera version that your entry resulted from. It made a very dramatic and powerful image in the end, I just felt it fell outside the boundaries we enter within, as I too can use a lot of those tools successfully, just not for competition time
oh well I guess but then again it was probably the worst of of the lot 
No 12 was a brilliant picture though so congratulations for winning it
