PAYG on the Overground (and on other NR lines where Oyster is

think this is true for the DLR as well.

Buses are different. $deity knows why, although my guess would be
technical implementation reasons rather than an ideological dislike
of mixed-mode bus-rail journey.

I looked this up on the TfL website and it seems to be true. I have
to admit I didn't realise.

It is valid for any pair of LU/LO/DLR/NR stations where the gates are
programmed for 'out of station interchange', or OSIs, however the list
of OSIs is not formally published. Station pairs explicitly linked on
the latest tube map, eg White City/Wood Lane, or Shepherds Bush LU/LO
are OSIs; as are implicit pairs like the two Hammersmiths. However it
is incorrect to assume all journeys involving a short walk outside the
barriers will be linked, but hopefully you have the picture now.

The current list of OSIs has been compiled by London Reconnections and
verified by TfL.

There seem to be a few glitches there, e.g.

London King's Cross LU King's Cross St. Pancras Met NR 30
London King's Cross LU King's Cross St. Pancras Tube NR 30

which should have NR and LU reversed, surely?

Also, I see there are still OSIs for:

King's Cross St. Pancras Met LU King's Cross St. Pancras Tube LU 30

and vice-versa are still in there. Surely they are no longer OSIs since
the Met station was reconfigured with the Western ticket hall?
