I can support that with my experience on the Piccadilly line with a
replacement bus between H&I and Seven Sisters - the tube barriers were
open to exit and enter the stations and no one touched in on the
buses.

I'm not quite sure when the Piccadilly Line served Seven Sisters. Leaving
the barriers open is fine for passengers who transfer from tube to
replacement bus then back to tube, but what about passengers who end their
journey at an intermediate station served by the bus? Unless it is made
clear that they must touch out when they leave the tube (although other
passengers are encouraged not to) they will get an unresolved journey.


I'm a little unclear as to what exactly "G" experienced, but if one
looks upthread one can read my account and in the case of what I
experienced - a replacement bus service between Acton Town and
Hammersmith - the gates were *not* open, so one had to touch-out/in as
appropriate. However what had happened was that the Oyster system had
been configured so as to mean that two legs of travel on the Tube were
counted and charged as if they were just one through journey.
