Yes, National Rail don't operate trains, but I suggest that you tell
TfL this, as their Oyster documentation and maps always seems to refer
to National Rail trains. If a person were only to look at the TfL
leaflets, they might think that Oyster PAYG is available on some
trains where it doesn't appear to be if you refer to the National Rail
information. The example being Harrow - Wembley Central on the few
Southern peak hour services

Are you saying that PAYG is not valid on Southern between these
stations? Where is the National Rail information that says this?
