66513 runs along the up relief line at Circourt Bridge, Denchworth, on 23 February 2017 with the 4L31 09:03 Bristol to Felixstowe North freightliner. Progress on the electfrication work here is painfully slow, and although it gives photographers a temporary reprieve, it does make you wonder why this kind of work takes so much longer than it did in the 1960s!
