Before I describe the attached pics, the following info may be of interest: in the latest on-line railway magazine, 'Railway Herald', (issue 14) the Slutchers Lane/Arpley area of Warrington is featured. Three pics of coal trains are shown (page 19) headed by locomotives 59201, 59206 and 70006. Go to the 'Railway Herald' link at the right hand side of the blog.
Regular contributor John Smith has sent in the attached pics, both taken at Red Bank, Newton-le-Willows. The first is of double-heading DRS class 20s, 20312 and 20313, working a Sellafield - Crewe flask train on 29th May, 2007.
The second pic is of double-heading Freightliner class 86s, 86610 and 86607, on a Coatbridge-Crewe container train also on 29th May, 2007.
