One of the new Mendip Rail workings from the December 2023 timetable change is 6A50, a 10:26 from Whatley Quarry to Hanwell Bridge Loop, running at a similar time to the old 6M20 to Churchyard Sidings. The train conveys portions for one or more destinations in the London area, usually Churchyard Sidings and/or Dagenham.
On 11 January 2024 66604 worked 6A50 past Manningford Bruce, on this occasion formed of a single portion for Churchyard Sidings. Not much change then!
