Harsco RGH-20C Switch and Crossing Rail Grinder DR79723 trundles very slowly along the down relief line at Circourt Bridge Denchworth on 10 February 2014, en-route from Reading Triangle Sidings to Gloucester Horton Road. It was following close behind a tamper, which was being held at Challow. This was lucky, as its slow progress meant it did not get in the way of the 6Z08 09:39 Llanwern to Washwood Heath covered steel wagons, hauled by 56094 & 56113, the tail end of which can just be seen in the distance.
