For any TOCs other than SWT or Silverlink Metro, the decision is still
in their hands, and probably depends on both TfL converting Oyster to
the interoperable standard (ITSO), and on TOCs seeing some advantage in
rolling out smartcard operation across their networks.

I wouldn't be too pessimistic, though. Southern announced last year that
they are committed to implementing Oyster prepay (with an initial pilot
scheme between Balham and Victoria), zonal fares are set to appear in
January (a pre-requisite for prepay), and I gather that Oyster-ITSO
compatibility trials are well under way.

I guess the other TOCs (and ATOC) remain unenthusiastic, but I noticed
that Peter Hendy said that any existing London TOCs who bid for the
Silverlink concession will be pressed on their wider plans for Oyster.

I still don't really see why the TOCs cannot widen their acceptance of
Oyster travelcards to include the one- and three-day types, in advance
of prepay - but I don't think it will happen.

I wouldn't consider a one-day travelcard as part of the same "range" as
a season ticket when I think about my travel.

No, but the increasing number of people who work from home and commute
to the office on only a couple of days a week (or less) do. It seems odd
that such people, who help reduce the amount of peak-time overcrowding
on the network, get so little encouragement from the current ticketing
arrangements.
