28th November 2015 One of the filthiest jobs on the rail network is the annual leaf mulch busting trains known as the Rail Head Treatment Trains (RHTT). Locomotives and wagons often spend the entire season with only a bare amount of washing carried out. As we approach the last few weeks of the leaf fall season, DB Schenker Class 66s No.66061 & No.66067 pass through Cogload Junction operating 3J13 08:45 Westbury - St Blazey (via Salisbury) on the 28th November 2015.
