Just to give this topic a boost, here are some pics of E27004 in blue and E27005 in green at Manchester Piccadilly on their last Saturday in service. They had all been withdrawn by the following Monday. Bit of a fluke really as we had been photographing fire-and-water machines at Chinley but the weather was hopeless (fortnight at f/2.8 with CT18) so went into the big city (well Manchester anyway) to see what was happening there.
Interesting to note that, of the two GUVs behind E27004, one is lined and the other apparently not.
