SR Rebuilt Battle of Britain 4-6-2 No 34077 603 Squadron (rebuilt in July 1960) with a down express climbing Grosvenor bank.
The headcode indicates that it is a Dover Boat Train via Chatham, Faversham & Canterbury East (ex LCDR route) which had been fully electrified in June 1959. I have seen accounts by someone who travelled on this service to Dover Marine, if I remember correctly with this loco - and I believe there was a short period in 1960 where this particular service was scheduled to be routed this way. Normally Boat Trains scheduled this way were formed of 12CEP/BEP+1/2MLV EMU formations.
