You can tell that autumn is not far off when the Rail Head Treatment Train wagons get moved from their summer resting place to the south of England. 66849 Wylam Dilly passes through Tackley station on 13 August 2026 with the 6W49 10:10 York Thrall Europa to Swindon Transfer, conveying a long rake of RHTT vehicles. Not only is it worth recording this working because of the lengthy train, but also once they have been in use for a few weeks the tanks will be brown rather than blue!
