Invisible train

I took this picture at shutter preference with shutter open for 30sec. I started the capture when the train just moved from the other station that I was able to see from the platform I was standing on. You see the concentrated light at farend becase of that. During those 30secs the trai reached this station and left. All you see if the lights between the plantforms of the station I was standing on and between their roofs.

Picture looks blury because there was so much vibration on the platform when the train arived and left.
