43031 heads south from platform 2 at Banbury on 2 January 2011, running 'wrong line' out of the station with the 1B20 08:15 Paddington to Carmarthen First Great Western service. The driver had just changed ends after arriving from the south via the Chiltern Line. These lengthy diversions were the result of an engineering blockade at Reading, which saw the line closed for most of the Christmas and New Year period.
