It's a long time since Class 321s worked this section
of line and even then it was the 321/4 subset rather than the 321'3s as seen here. De-branded 321324 and 321301 are close to their destination as they pass Milton Keynes being taken to Wolverton Works after a lengthy period of storage in Wembley Yard. Up at the front Rail Operation Group's 37800 'Cassiopeia' were towing the pair of former Greater Anglia 'Dusty Bins'.
