I take it that interavailable routes will still remain on the LU
farescale? Ironically this might make South Ruislip - Marylebone
cheaper than Northolt Park - Marylebone.

The fare changes in the New Year do give rise to some intriguing
situations occurring. For example, and correct me if I am mistaken,
there is a special set of fares for a journey combining National Rail
and TFL, so would one have to pay a different set of fares for the
following journey depending on which mode of travel you used ?

South Ruislip - Oxford Circus

Route 1: South Ruislip ( Chiltern ) Marylebone ( Central Line) Oxford
Circus

Route 2: South Ruislip ( Central Line) Oxford Circus.
