Yesterday I posted an article giving details of all the Class 67 Silver Train times (and also the old blue and grey train) operated by Chiltern Railways.
At the foot of the article I placed a caveat which might be summarised as 'maybe'.
Today is a maybe day.
The 0744 from Princes Risborough is the old blue and grey set today (more seats for Beaconsfield).
Thiscould mean that the 0845 from London Marylebone to Birmingham Moor Street will be the same old slam door train with no Business Zone, though with other Silver Trains due to arrive in to Marylebone at around the same time I suspect that this will not be the case. Some swapping of trains will probably occur.
The 0750 from Banbury is apparently a 168 'Clubman' today.
Basically - for today, ignore my article of yesterday because the morning Class 67 trains are all over the place!
