Over the years I have got pictures of various classes of locomotives bringing coal down to Didcot Power Station from the north. However, Freightliner Class 66s are a bit of a novelty, so I was keen to get a picture of the recently introduced 6Z98 12:57 Daw Mill Colliery to Didcot Power Station working whilst I was at Upper Heyford on 23 March 2011. So here it is, headed by 66554 and heading down the Cherwell Valley in the warm spring sunshine.
