Plagiarism is the highest form of complement. There’s a RR Illustrated/CTC Board article with this shot in it. This looks to be a risky photo to take and I asked the photographer how he got the shot.
He explained and it was really quite easy. He copied what Dale Sanders had done. So I copied the shot as seen here on 6/8/12. It only looks like the picture is taken while standing on the tracks.
