I've stood on this platform at Stratford station many times and always look up to appreciate the colour of the rust on the pedestrian bridge which spans the tracks.  Usually I'm in a rush but yesterday on the way home from a shoot in London I had time while I waited for a train to take this photograph of the reflection of some of the structures in the Olympic Park.  I do have a degree in Civil Engineering, but fortunately after graduating I soon switched careers to something that didn't involve endangering the life of anyone who may have had to cross a bridge built to my specification, or of anyone standing underneath it.
