I can also confirm 1H47 15:55 Birmingham Moor St to Marylebone was a 68 today.
Do we have a new Summer Saturday Diagram?
All your sightings in this thread sound more like temporary strengthening in connection with theCan confirm 1G27 11:40 Marylebone to Snow Hill is 68008 this morning.
And going on OpenTrainTimes live. It would of Worked 1H13 this morning also.
I believe that this may well be a new Diagram, because it was a 68 last Sunday also.
Depends what you mean by "always" - any of the Chiltern 'silver' services can be operated by unitsOn Weekdays, are the 1010 and 1110 from Marylebone to Moor Street & the 1555 back to London always operated by the loco hauled trains?
If you look at the weekday Diagrams, you will see all of your timed departures are in them.
Chilterns 68 fleet is a bit hit and miss at the moment. But i am now on over 26,000 miles for this year out of them.
