As some may know, I have Cambridge - London Terminals season ticket
and commute daily to Moorgate, using LU between KX and Moorgate.

I can confirm my ticket gets rejected by the gates at Barbican and
Farringdon (on the occasions when I tried that I used my pre-pay
Oyster instead to leave the station: that was in the days when you
weren't penalised for an unresolved journey).

If I had such a ticket I would certainly have tested the gates as you
had done out of pure curiosity! You can of course perform such tests
if you are also in possession of a Day Travelcard or even an LU single
printed ticket - indeed you could also do so if you were willing to
take the £4 unresolved journey 'penalty' (though technically given
that the National Rail ticket isn't valid at intermediate one would be
breaking the strict letter of the rules).


However my ticket *does* open the gates at St Pancras Low Level,
despite my ticket not being valid there. (I only ever do this on the
occasions when KX Underground is closed due to overcrowding and
passengers are asked to divert to nearby stations).


Which would support a thought I had in my head - I'd wager that FCC
have merely copied the rules they used for the gates at KX Thameslink
and are using the same ones, unamended, for their new gates at St
Pancras Int'l low level. If this is the case then the London Terminals
tickets from points south that were erroneously accepted by the gates
at KX Thameslink might well also be accepted at St Pancras low level -
unless the rules were specified more tightly at some point since then.
