 I don't wish to tell AWC Control how to run their trains but I have a question. A few minutes before this image was taken, a pair of old, dirty and noisy Class 221s headed south through Roade cutting on a Chester to Euston service. Now 805009 and 805003 head south with the 16.21 Birmingham to Euston service. Why roster the 221s on the Chester train and the 805s on the Birmingham one?
