David J Hayes adds "As I've mentioned before elsewhere, the evening Willesden to South Wales Freightliner would appear to have often displayed the wrong headcode on the initial leg of the journey to Kensington Olympia (where it ran-round), as further demonstrated here. Although pre-dating this image, timings contained in the October 1969-May 1970 WTT show that 4V64 was booked off Willesden FLT at 20:20 SSuX and running round at "Kenny-O" from 8:32-9:05pm (it may have still been running to this schedule when this image was taken). The service was also shown as running to Swansea Danygraig, although it may have also called at Cardiff Pengam as well."
