During my vacation I got the chance to capture a clip of a passing train in Jasper, Canada.
The setup used was slightly different, as a Canon 60D was used to capture the 7,5 minute long clip instead of the GoPro mentioned in the previous posts.
Because of the length of the train (140 wagons) the resulting picture got quite wide. Shot at 50 frames per second with a vertical resolution of 1.280 pixels the result got a dimension of 23.479 by 1.280 Pixel.
