What absolutely isn't acceptable is requiring passengers from Leagrave, Harlington, Ampthill, Bedford or passengers from the Marston Vale Line travelling to the north having to use a rail replacement bus service between Bedford and Wellingborough.
And as I keep pointing out - the numbers joining such trains at Bedford are minimal - penny figures in fact.
And that's joining at Bedford i.e. could have come from further afield.
So - once again, the timetable change is about what works best for the majority of people.
The majority of people from Bedford are travelling south - there will be far more seats on southbound departures.
The majority of people travelling from Wellingborough and Kettering are travelling to London - they will benefit from (i) the chance of getting a seat is far greater because the train isn't being filled with commuters from Bedford or Luton and (ii) potentially a slightly quicker journey time.
People travelling longer distances - Leicester, Nottingham, will also benefit as they are more likely to get a seat - which given the fares they are paying isn't unreasonable, rather than having to stand for 30 minutes until the half the passengers leave at Bedford.
The bustitution is temporary - driven by platform constraints at Bedford and the infrastructure works that need to be done between Bedford and Kettering - once that's done Bedford will have a 2 tph service north to Wellingborough and Kettering on electric services.
The only remaining question is where EMT's longer distance services should stop - and I'm sorry, but the obvious answer is Luton Airport - to provide a link to the airport and Kettering, to provide the link to the electric service. That would be very similar to the situation on the ECML where you have Stevenage and Peterborough used as the VTEC link and the distances are similar - ideally EMT's first stop after Luton Airport would be Leicester, but that's not practical as there is the need to provide a link to intermediate stations and also serve Market Harborough, so by virtue of its location, Kettering is the logical place.
