The two pics of the class 87, 87002, painted in the purple/mauve Porterbrook livery are scans of early photographs which display acceptable quality. The locomotive is heading Virgin passenger stock in both shots. The pics were taken at Winwick on 21st May 2004 and 3rd November 2004, and show both sides of the locomotive. The photographer was John Smith. The locomotive was named Royal Sovereign between 1978 and 2003. In the latter year she was reliveried into the purple/mauve livery of its new owners, Porterbrook Leasing. It remained nameless until 2005 when it was renamed The AC Locomotive Group, its present owners.
Pic number three is from Ken Young and shows double-heading, light engine Freightliner class 66s passing through Warrington Bank Quay on 21st July 2010. The first loco is 66620 but the second one is hidden behind.
The final shot in this post is from Jeff Nicholls. Freightliner class 70, 70003, is depicted at Sankey Bridges on an Ellesmere Port - Fiddlers Ferry coal working. The date was 7th October 2010.
