Sita UK have redeveloped the old ICI chemicals plant site at Severnside, building a generating plant that will burn household rubbish. Paths have appeared in the working timetable, but as far as I'm aware, as of May 2016 no trains have yet run. However, on 16 May 2016 a train did run the path of the 6A03 05:14 Severnside Energy Recovery Centre to Brentford, running instead to Acton. This was actually the wagons from a stone train that had been cancelled, causing the empty wagons to end up at Avonmouth. This working was used to get the wagons back to the London area for their next working. Luckily this was running over an hour late when 66089 passed me at Compton Beauchamp, resulting in a much better lighting angle.
