43153 passes the site of Challow station on 4 December 2015 with the 1L36 08:31 Cheltenham to Paddington GWR service. The morning was nothing like as sunny as the Met Office has predicted, in fact the cloud seemed to roll in from the west as soon as I had got the car out of the garage! However, when the sun did appear, the lighting was spectacular, with an impressive background of really dark clouds.
