Bearing in mind that the original question is from a newbie to the
group, using such terms as OSI in a reply is stupid IMHO

I was answering Roland who is a regular here. The OP seemed to be up to
speed on the risks.

I know an OSI is an 'out of station interchange', but what's an OEP?

Oyster Extension Permit - an unwieldy device invented at the behest of
the TOCs - pax who have a *season* Travelcard loaded on their Oyster
card but want to go outside the zones covered by said Travelcard are
supposed to get one before they start their journey.

I omitted to mention - only if said journey is on National Rail.
There's no requirement to use them for 'out-of-zone' Tube journeys.


There's an explanation on this webpage - see under "How to use a
Travelcard and pay as you go together on National Rail":
http://www.tfl.gov.uk/tickets/oysteronline/5823.aspx

Given that many NR ticket offices and ticket machines can't 'issue'
OEPs on Oyster cards, the whole concept is a bit of a shambles. If I
wanted to make such a journey but couldn't get an OEP first, I
wouldn't have any qualms about going ahead making the journey anyway,
touching-in and out as per normal.

It appears to have been much discussed on utl recently, though I
wasn't around here at the time and haven't (yet) gone back and read
through the relevant thread.
