Careful - I am almost certain that BZ6 tickets are *not* valid on
Virgin trains.

I am no expert - does the following help?
The Freedom Pass site makes the following statement.
Quote
The freedom pass is NOT valid for travel on train services operated by
Arriva CrossCountry, Grand Central, Hull Trains, East Midlands Trains,
Gatwick Express, National Express East Coast, Virgin Trains and
Heathrow Express, or on Heathrow Connect between Hayes & Harlington and
Heathrow.

I think that this rule is identical to the one that at least used to be
applied to travelcards.

You can get a Travelcard from EMT for stations Kettering and further
south, so they aren't a "travelcard free zone".
