The machines are confusing, even for someone who knows what he's looking
for. There should be a "not Gatex" fare to City Thameslink, as well as
to "London terminals", but whether the machine displays it without a
fight is another matter.

Since City Thameslink is a member of London Terminals, those two
tickets are one and the same. Presumably the machine offers London
Terminals tickets if you select City Thameslink.

There are other oddities too, for example the "FCC only" ticket to
Farringdon is actually marked "Not Underground" (on the ticket, who
knows what the screen says). In practice the only extra flexibility that
this apparent re-naming gives is the ability to change at Croydon.

IIRC it also allows the route Gatwick - Clapham Junction - Waterloo -
Waterloo East - London Bridge - Farringdon. (Obviously the only
practical usefulness of this is that it allows you to start/end the
journey at Waterloo.)
