Due to engineering works, the 6A11 22:49 Robeston to Theale Murco oil tanks was diverted away from its normal route via the Berks & Hants line on 16 July 2013. Instead it travelled via Swindon and Didcot. Luckily its two hour early start had been reduced to just a few minutes early running by the time it passed Challow, as 05:42 is quite early enough to be out taking pictures! With no other trains around at this time of day, it has no need of the relief line, and 60062 Stainless Pioneer is pictured passing the site of Challow station on the main.
