Can anyone explain in two sentences why, if someone has a NR return ticket

allowed to leave at Farringdon?

A ticket from London Terminals is a ticket from KXTL (for northbound
journeys) or City Thameslink (for southbound journeys). If you want to
extend the journey to/from Farringdon, you have to buy a more
expensive ticket to permit the extra travel.


But a London Terminals ticket *is* valid from St Albans to Moorgate,
isn't it?


Barry Salter explains that this ain't so in his reply to your post.

Of course London Terminals tickets are valid at Moorgate for journeys
from/to the FCC Great Northern line.
