Ghost train

Trying to work out the manual controls on my D5100, playing around with the aperture, ISO, exposure length and timing of the shot on trains that pass through Acton Bridge station so that so time in the future I can try it on during darkness but in the mean time this is the closest to what I had in mind - the train was far enough away from the camera point no to tkae over the picture as others did as they passed the paltform I was standing on - not sure if the train will fade back into the backgound the more I leave the exposure period on thats something to try next time
