A continuation exit is where someone swipes their Oyster card at an
intermediate stop on their journey but in fact is not exiting at that
particular stop.

e.g.

Joins the underground at Moorgate get to Bank and goes to the DLR platforms
and swipes their card again at readers there. The system would assume at
this point that the person has exited at bank because they swiped in at
Moorgate and the second swipe at bank would be an exit. However the person
continues to their destination and swipes it on their 'real' exit and the
system automatically recognises the middle swipe as not the real exit.

Stations where which have this probability include Farringdon, Barking and
other interchanges. They are known as Continuation exit stations.

Without knowing your exit on DLR I cant be sure what has happened but if you
put your card on the big ticket machines or get a printout at the ticket
office it will show the last 8 journeys.

Ok - maybe slightly weird 'feature' of Oyster, or just me and the DLR
captain being stupid...

Today, I had to pop home to pick up something at lunchtime. So, got the
DLR
from Bank using my Pre-pay Oystercard to swipe in through the gates.

Got to my stop on the DLR, walked out and swiped my card again to say that
I
was leaving - and checked that it actually did register.

Picked up what I needed to get and literally got back to the DLR for the
next train back. Went to swipe in again but this time it still said 'exit'
instead of 'enter'. Thought that maybe I was going made and had misread
the
machine when I left and it hadn't swiped properly on the way out so I had
just registered my exit and not entrance onto the DLR (are you all still
with me?). So, I swiped it again. And it still said 'exit'. After a
third
time it said 'Seek assistance' (which is great on an unmanned DLR
station).

Anyway, when the train came I was lucky enough to be at the door with the
DLR captain/ticket inspector so I asked her to check the card. She
checked
it and said that it said it was registered as a 'continuation of exit' but
had no idea what that meant. As I didn't want to get stuck at Bank, she
reset the card register as the start of a normal single trip.

So, does anyone know what this all means and what would've happened when I
got to Bank? Would it have registered the journey as Bank - Bank and
only
charged me for a zone 1 journey (instead of the zone 1 - zone 2 journey
that it really was).
