First Capital Connect has announced that, from January 2007, as part
of the introduction of zonal fares that all their stations in Zone 1
including Farringdon will be classed as London terminals when buying a
ticket. This means that Kings Cross will now be classed as a London
terminal when travelling from the south, and City Thameslink,
Blackfriars, London Bridge and Elephant and Castle will now be viewed
as London terminals when travelling from the north.

Is this for the "line formerly known as Thameslink" only, or for Great
Northern as well?

For FCC services on the Great Northern route, King's Cross and Moorgate
are London Terminals (using LU services if desired) but Farringdon is
not, unless things have now changed.
