Did you touch out at Wembley Central? *If you didn't then I can fully
understand why a touch in at Wembley Stadium would, in fact, end your

It should still allow an onward journey though, shouldn't it? My
understanding is that if you touch a free-standing validator your
journey is still able to be reopened - so if he'd have touched out at
Marylebone it would extended the end point of journey. This is
certainly how it's behaved for me.

No - there's *no* OSI between any of the Wembley stations, therefore
touching on a reader at Wembley Stadium station with a card that has
an open journey will finalise that journey.

Also, free-standing validators seem to be configured in one of (at
least) two modes - one is "interchange mode", where it keeps open the
possibility of your journey continuing for a set amound of time. The
other is "straightforward mode", where journeys are either started or
finished according to the state of the card - full stop, no
possibility of journeys continuing.

In my experience most DLR validators are configured in
"straightforward mode" (for want of a better term!), though a few are
in "interchange mode" - apart from OSI situations, I think a few
others might be such as at Poplar where you have to pass across the
overbridge and past the free-standing validators to change from
platform to platform.


Or in other words, the gripper's machine (or the gripper) isn't
programmed to detect this state.

See above.


Speaking of incorrectly programmed Oyster machinery, last week I took
a train from Stratford to Tottenham Hale to use the Victoria Line, but
because I went straight to the tube gateline without first touching a
validator on the NR platforms, I was charged £4 for the train journey.
Grrr.

Annoying, but strictly speaking that's correct - from NR platforms to
the Victoria line station is an OSI, therefore you're supposed to
touch-out beofre you then enter the gates and touch-in again. In this
instance it would be good if the LU gates had some tolerance though.
