Well certainly with the NFM02 time restrictions anyone travelling from
Preston for example who thought they might need to leave London between
3 and 6 would have been a fool not to have bought a Lancaster ticket.
And maybe Virgin saw that, maybe they've noticed a lot of people doing
that these last three months anyway. That said it is more than that
route I think, its quite a list of restrictions, off sick from work so
can't remember right now. Ultimately it must come down to perceived lost
revenue.

Bringing up an old subject, but isn't starting short on non-Advance
tickets considered to be different than BoJ?. So it's prohibited to
start from Lancaster, break off at Preston then resume the journey later
but ok to start at Preston on a Lancaster ticket?

Of course, with multiple TOCs serving the two stations, neither of which
have barriers, who is to say you haven't just changed trains there
anyway?
