Thanks all. I had thought that DOO on the tube was a 1980s phenomenon.

minor nitpick

Its not called DOO on the underground, its called OPO. Well at least
its called OPO all the lines I'm involved with, which at the moment
does not include the Victoria. OPO is One Person Operation and applies
today on all lines whether ATO or not.

However, the rest of the answers above stand, Victoria was ATO with
only a train operator from the start.
