With the early morning mist still hanging over the hills, 43320 National Galleries of Scotland passes Tomatin on 8 October 2007 with the 1E12 07:55 Inverness to Kings Cross 'Highland Chieftain' GNER service. This was one of the earliest Class 43 renumberings, emerging from Brush at Loughborough in January 2007, after being fitted with a MTU engine and having its former 43120 number changed to 43320. The simple formulae for all GNER (later National Express) and CrossCountry renumberings being to increase the number by 200.
