20302, 20306, 20310 & 20307 pass Brock with the 6K73 15:38 Sellafield to Crewe nuclear flasks on 6 May 2008.

This was one of those annoying occasions when the sun went behind a cloud just at the critical time, however careful use of Photoshop has insured that the correct amount of detail is retained in the sky area, instead of the dreaded blank sky that normally results from such conditions.
