66769 Challow 4 January 2019

66769 coasts along the down relief line at Challow on 4 January 2019 with the 6V30 09:49 Grain Thamesport to Margam steel empties. This was running exactly to time, and stopped here for the booked 18 minutes. However, in South Wales it didn't stop at Llanwern as booked, and consequently passed Cardiff 87 minutes early!
