This proved to be the most time-consuming photograph of the session to prepare; it took me four attempts to get it to this stage.   Firstly, in order to try and avoid a burnt-out skyline, I shot the image slightly underexposed, so I had to compensate for that.   Then I had to get rid of some background clutter, mainly a person just on the other side of the crossing and vegetation on the left side of the photograph (I had planned to try and eliminate the latter completely, but settled for just cutting it back from the train itself).
