Having just emerged from Wickwar Tunnel, 220007 heads south on 15 April 2015 with the 1V49 09:07 Manchester Piccadilly to Bristol Temple Meads CrossCountry service. The second vehicle seems to be painted in a slightly darker shade of grey to the rest of the train. It's not a trick of the light, as several other pictures that I have seen of 220007 from around this time also show it.
