This photo was sent to me by John Passells who took a quick snap before being caught which is why it is blurred.
It shows in the distance the Russian Svedlov cruiser Ordzhonikidze arriving at South Railway Jetty in Portsmouth Dockyard in 1956. The photo is to me more poignant as it shows the entrance to the railway viaduct linking the jetty to Portsmouth Harbour station. I have never seen the viaduct from this angle before. It also shows the gates protecting the viaduct from the general public.
