66729 Derby County passes Shrivenham on 18 February 2015 with the 6B11 12:20 Colnbrook Lafarge to Pengam stone empties. This had left Colnbrook over half an hour late, and was delayed even further in the Hayes area, running over an hour late at one point. So it was doing well to be only five minutes late here, and even better to arrive at its destination nine minutes early!
