Had the LT Card survived, that might have been of use for this, but I
don't see why anyone would buy one as ODTCs, certainly off-peak, were
better value.

So another good case for TfL to take immediate control of National Rail
fares in London and harmonise them in line with the Tube (i.e. zonal and
not point to point).
