What would happen anyway - if you were stopped with prepay on the train then
I guess it wouldn't be valid when they checked it but if you weren't stopped
and walked through the barriers you'd be allowed out but I presume you'd
have an uncomplete journey so not be allowed back in the next time?

My guess is that, unless you were stopped on the TT service, you
could get away with it. Indeed, many people might manage to do it
without realising they were doing anything wrong. Last time I was
at Ealing Broadway, you could freely walk between the TT platforms and
the LUL platforms without going through a gate. That leaves the
problem
of how to touchin the card at Paddington: you could take the circle
to Paddington, get out and touchout; walk to the metropolitan
platforms,
touch in and walk away then walk to the TT platforms.

All this touching in and out of Oyster cards has got me confused: they
seem to have little idea of how the system is supposed to work at
interchanges,
especially those where you have to leave the station and walk in
another one.

There was engineering work on the circle line a few saturdays ago. I
arrived
at Tower GW DLR and walked to Tower Hill. I was told it was closed and
I
had to walk to Aldgate instead. I did this and was surprised to find
that the
Oystercard had treated it as a valid interchange. How did it do this ?
Somehow,
I can't imagine Oyster being reprogrammed just for engineering work.

The problem with Oyster prepay is that you don't have to commit to
"purchasing"
a ticket for your entire journey at the start of it, so does anyone
know what
would happen if you took a journey from Hammersmith to Uxbridge
without
going through Zone 1: how would Oyster know how much to charge when
you got
to Uxbridge: it wouldn't know whether you'd come via Baker Street or
North Ealing. With a paper ticket, you'd get PFed for traveling on the
more expensive
route with the cheaper ticket but with Oyster Prepay, this is not
possible
as you haven't been asked to commit to a price yet.
