Cambridge depot's set 20 (54372 & 51443) passes Great Paxton on 20 September 1986 with the 07:37 Hitchin to Peterborough service. The extremely early time of day explains how it is possible to have the sun on the front of a northbound train on the East Coast Mainline. The Western Region did not posses many Class 101 units until the late 1980s, and indeed this shows a unit that would soon be moving to the Western. However, it would not remain together as a single unit, the front vehicle (54372) would form part of unit L202, whilst the rear car (51443) would find itself in L205. The original 6x7 slide of this image unfortunately looks nothing like this, as it is one of the few (luckily) pictures that I took on Agfachrome 200RS. It has now turned completely purple! Luckily Photoshop has once again come to the rescue.
