MML still accept off-peak Travelcards in the evening rush, so this may
shift even more of the Luton/Bedford crowd off Thameslink and onto MML.

Are you sure about that? I just complained to FCC about the fact that
their new pocket timetables no longer show the morning peak restrictions
with darker shading, as all Thameslink ones did (and their own first
attempt did also). In their reply they also told me about the new
evening peak restrictions, which they say also apply to departures from
St.Pancras - and only MML runs trains from there.

I will check by emailing MML customer services, but they usually take
ages to reply, which means getting an answer before the restrictions
come into force is unlikely.
