This would have been a week prior to 6000 going into Swindon Works for an unclassified overhaul and just six months before its withdrawal that December, following which it spent six years in the Stock Shed at Swindon before restoration and eventual return to the main lne in 1971.
The last years saw the remaining " Kings ", all now at Old Oak Common or Wolverhampton Stafford Road, working the Birmingham line from Paddington and I wonder whether 6000 had failed here at Banbury on such a working.
