Note that from Bedford at least, an all day travelcard is cheaper
than a standard return to Zone 1, so will be issued if anyone asks
for a return to a Zone 1 destination.

Is that still true with the evening peak travel restrictions now?


Sorry for the confusion, the naming isn't entirely clear,
an 'all day travelcard' is the peak version,
a 'one day travelcard' is the off-peak version.

Before the January 2006 fare changes, the all day travelcard was more
expensive than a standard (peak) return to U12,
but since then it has become cheaper, so there is now no requirement for a
return to any tube station, as the travelcard is cheaper.

The new evening peak restrictions do not apply to this ticket, as it is a
peak ticket anyway.
