A frosty morning at Tackley on 16 February 2008. 165126 accelerates away from the station with the 07:53 Oxford to Banbury First Great Western service. Just ten minutes behind it was something much more interesting, and much noisier - D1015 Western Champion with the Pathfinder Tours 1Z15 06:00 Ealing Broadway to Holyhead 'Irish Mail' railtour.
