great shot! I don't mind the center column at all...the only thing I may have changed would be a crop of the left side, just to get the trash bins or whatever they are out of the shot. this is a great photo! is this in the netherlands?? they've got some big yellow trains over there.
To me, that strong center column helps because it lets the train rush PAST something. This images makes me feel akin to how I feel when standing at a train station and some train zooms through the station without stopping. Perhaps if the center column was not so centralized in the frame it would not be as dominant, but as is the image works for me.
This shot really translates speed. It's almost an illustration of the principle of relativity. The train is a featureless yellow tube, glowing through space, and time. What distracts from that strong subject is the central column. Also, the neons are burned and weaken the compo. I wish you would have given more technical details.
