37796 takes the Cumbernauld line at Greenhill Lower Junction with the 6D52 15:38 Aberdeen to Mossend Enterprise service on 27 April 1998. Falkirk in the distance has just received a heavy shower of rain, which can be seen moving off to the right, complete with a tiny section of rainbow near the horizon. The low evening sun is often a problem for loco drivers, just as it is for car drivers and one frequently sees copies of the Sun (or presumably the Daily Record in this part of the world) used as sun visors. This looks to be even more improvised and close up study of the original 35mm Fujichrome slide shows what looks like a scrunched up old Tesco carrier back roughly stuck in the window.
