Strange goings on at Challow on 21 March 2020. Instead of slowing down, prior to coming to a stop at signals just behind me, 66604 is pictured travelling at speed along the down relief line with the 6B91 12:34 Hayes & Harlington to East Usk Yard stone empties. It went into the loop at Wantage Road, and straight out again at Challow. With far fewer GWR passengers trains operating, due to the Coronavirus crisis, there was no need to do this, as nothing passed it while it was on the relief line. This naturally converted its 17 minutes early running to 52 minutes!
