Captain, could not disagree more, dweeb where have you gone wrong. It is to dark, moody some would describe it but I agree with Ken it is just to dark. In pouring rain , mist railway photographs can be well captured and worked on but to me you need something to work with and for me it looks like there was not a lot there to try and make something of.
But at least you have had a go, but its all about keep going back, when you get a shot in great light and exhaust you will look back on this and think why did I bother. I speak from many years of experience, but credit for having a go.
