66054 passes under the signal gantry that controls the double crossovers at Bourton (near Swindon) as it heads west with the 6B24 10:36 Didcot to Wentloog MoD stores on 4 February 2009. Snow had fallen during the night to top up the previous day's covering, so with the sun shining I set off for the Great Western Mainline hoping for some excellent photographic conditions. As I drove towards the line the sun just got weaker and by the time 66054 appeared it had virtually gone! Note the remains of the white painted sighting patch on the bridge in the background, a relic of the days of semaphore signaling. This section of line was converted to automatic colour light operation in 1965.
