Few of us ever really look at the inside of a Toronto subway tunnel, especially at the speed the trains rumble through. This spectacular shot, posted to the UrbanToronto Flickr pool by Ben Roffelson, gives us a glimpse of the dark and dingy tunnels our trains pummel through. The blurriness of the lights and the passing train also highlight the fact that capturing such an image is no easy feat.
