Bob McClellan (2) and Geoff Monks (1) have forwarded three pics for todays post (28th October 2010) showing two locomotives in each pic. All six locomotives are from just two classes.
Pic one from Bob shows DRS class 47s, 47298 and 47802, double-heading, light engine through Winwick, southbound, on 8th February 2004.
Bob's second shot, taken on 7th December 2004, features weathered EWS class 37s, 37706 and 37682 on the water cannon train.
Geoff's pic is of WCRC duo of class 37, 37685 and class 47, 47760 heading to Blackpool, on 2nd October 2010, to head a Kiddermister - Blackpool charter, originally headed by 'Jubilee' class 4-6-0 5690 Leander, back to Kidderminster. The locomotives are on the northbound slow line where they were held at signals, waiting for the charter to pass on the main line.
