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.

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.
