I spent about an hour trying different compositions of this building, and in that time three trains went by. When I heard the whistle blow in the distance I quickly set up for this shot as close to the tracks as I 'thought' I could safely be. I started the exposure about 10 seconds before the train entered the frame and took a couple of steps back. What I didn't realize is that this train was quite a bit longer than the other two and moving at around 60 mph! The strap on the camera started spinning like a helicopter, and all I could think of was my camera getting sucked under the train, so I dropped to one knee and grabbed one leg of the tripod and held on until the train passed, which seemed like an eternity! I thought for sure the shot would be blurred out but to my surprise the camera never moved.... Get Really Close Canon 5D Mark ll EF 24-70 @ 38mm f/13 ISO 400 30 sec exposure
