So the images are actually just the result of long exposure shots from the New Transit Yurikamome an automated guideway train that connects Odaiba to the mainland, in Japan, passing through the Rainbow Bridge.
The photographer is Yurikamome, and you can view more of his work on his flickr page.
I just love how the colors all merge together and everything becomes so smooth. But the best part is how he managed to portray intense speed in a still image.
The fact that these images were shot in Japan doesn’t hurt either.
