Oyster Extension Permits

All the discussion appear to centre around what happens if you set an
OEP then fail to use it. If the TfL advice is followed, that should
never happen - you only set an OEP if you are going to use it.

It's like me buying a CDR to travel to Manchester and back then
changing my mind about travelling. I've lost the money I have paid,
unless I go through the refund procedure.

When planning the use of a complex product like Oyster, there will
inevitably be interactions that have not been fully thought out.
Perhaps they should abandon the whole thing, and we all go back to
'one journey, one fare'!

But what if you only realise that the trains have been cancelled *after*
you've set the OEP. Look at the thread describing the chaos at St
Pancras on Saturday afternoon, for a flavour of whether or not an
expectation of being able to travel is a fixed, or variable, feast.

You do the same as anyone with a regular NR ticket. Get it cancelled
and refunded.

It's not really the same. The NR ticket can't be used on a different
day, plus you don't pay for the OEP, but it does make you liable for
future charges if you aren't careful. If you are careful and don't
have to make certain types of journey, it sits there till you need it
and you can use it on a different day.

But can they be cancelled? If they can, then the advice to add one
only when you intend to use it makes sense. If circumstances change
and you don't use it, then you get it cancelled and buy a new one next
time.

You can only go so far in making systems idiot proof. There is always
an idiot out there that can fool them.

Not really, at least not in this case - at London Bridge, one has to
exit from the tube station and will therefore pass through the LU
ticket hall.

And what if it has an inconveniently long queue (such things are far
from unknown)?

OEPs can be set (and removed) at *any* Tube self-service ticket
machine, as well as at the ticket office - there'd be one available
without too long a wait at either Bank or London Bridge.

So it's better than KX/StP, where the queue for the machines is
sometimes ten deep.

[1] Somewhat bizarrely the London Overground Shere TVMs I checked in
the past week didn't appear to be configured to issue OEPs though.
(And yes, I know there's no requirement to use OEPs when making
'extension journeys' on LO, but I'm pretty sure I read some blurb
somewhere that said all TfL outlets inc. LO ticket machines could set
and remove OEPs.)

The DLR machine I tried at Langdon Park last month similarly didn't offer
OEPs; instead you could get a paper extension. I've not tried Overground but
will look at Wanstead Park when I next pass there - the GOBLIN *does* have a
need for OEP availability because a passenger may want to travel onwards
from Barking.

Yes, they can be cancelled at LU stations and supposedly shops, if
they've heard of them. I don't know if I could face the conversation
at my local shops.

That I can understand!

Bank or London Bridge, doesn't make any difference so long as the OEP
is on the card before the NR part of the journey. (And no, I don't
think loading an OEP onto the card mid-journey at London Bridge would
make any difference to the whole journey being treated and charged as
an LU+NR through journey.)

I assume though that at London Bridge anyone adding an OEP has to go out of
the barriers though? What about at a station like Stratford where there are
machines inside the barrier line, on the Jubilee side of the concourse. Can
one add an OEP and then use the platform readers to register it mid journey
or do they have to go out of the station?
