37883 reaches the end of Arnside Viaduct with the 7A73 17:21 Sellafield to Willesden nuclear flask on 23 July 1997. Despite the awful weather, I particularly wanted to get this picture, as I had correctly worked out that the very short train would fit in the available gap, without the 30mph speed restriction sign getting in the way. The viaduct crosses the estuary of the River Kent.
