Estimated date but still with worksplate. I remember at morning rush hour a couple of 33's and 73's terminated with MK1s at London Bridge - Loco hauled peak workings were mainly from East Grinstead or Uckfield to London Bridge and class 33 hauled, they lasted until about 1984. This however is a Brighton to London Bridge peak working whilst the 4CEP units were away at Swindon for refurbishment. The loco was released by another stabled on a short spur.
