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.
