Don't play on the tracks!

I wasn't; I was walking along the maintenance walkway at the side of the track. Halfway to the centre of the bridge and back again. I had just stepped off the walkway when the freight train came along allowing me to get this picture:

The scary thing was how much of the walkway the freight train took up - I had thought I would be safe against the hand rail but, no way. Another photographic near miss :-(
