So now that Oyster PAYG is accepted between Victoria and Balham there
are lots of posters up at stations, and announcements at stations. But
none of them that I've seen/heard mention OEPs, so not only are they
hard to understand, they're being kept secret too!

I thought they were coming later, for further extensions e.g. into
SWT-land? They aren't used in LM-land at present.

OEP are to do with extending a travelcard outside its zones, but only
within the overall London Zonal area. AIUI it is a TOC driven requirement to
attempt to deal with pax not touching out. For example, using a Z1-2
travelcard season to enter the system, then not bothering to touch out at
their final destination, say in Z6. The basic TfL system, using normal PAYG
for extensions, accepted the risk of this fraud, because nearly all their
stations have barriers.

However getting back to the OP's point, if my understanding is correct there
may be no need for OEPs yet in Southern's trial area, as it could be fully
barriered?

There hasn't been any indication of Oyster operating way outside the London
zones, except for Watford Junction as now, and a few c2c stations. SWT's
system outside the zones is ITSO spec, as required by DfT.
