As a slight divergence from normal blog subjects, and to be more inclusive, I am using three light engine pics in this post (28th June 2010).
The first is from Andy Appleton, taken on 6th August 2007. Class 31, 31459 Cerberus is shown, southbound, at Winwick. This locomotive has been described and photographed in previous posts, (9th February and 21st March) topping or tailing NR test trains.
Jeff Nicholls' pic of class 47, 47851/D1648 Traction Magazine was taken at Bank Quay Station on 3rd September 2005. This locomotive has also been included in a previous post - 4th March.
The third and final pic is one taken by myself on 26th March 2010. The class 70, 70006, was travelling northbound through Winwick. This locomotive, and others in the class, have been seen quite regularly this year in the general Winwick area; 70006 was featured in 24th May and 21st February posts and described in the 8th March post.
