My job is to drive the train not record passenger loadings. I haven't yet had a day where I have had any less than 300 leaving liskeard that is all I can confirm. I don't remember specific numbers like 415 one day and 380 the next. The figure of 300 is very much the absolute minimum, it is usually closer to 400 or more. So if you want accurate figures I can't provide them.
And whilst it is true some get off at Plymouth, this will still equate to some passengers standing for more than 20 minutes which is what the dft tries to avoid.
And whilst it would rarely fill 650 seats , this goes to show the train lengths specified where all wrong. A mix of 5, 7, 8, 9 car sets would of made more sense if trying to match actual seating required for individual services.
So the story changes yet again.
Now it's 'usually closer to 400'. I bet it isn't in the depths of winter on those days that you have previously conceded were not busy.
Is it any wonder that I and others are sceptical about some of your claims about loadings in Cornwall, given the lack of accuracy in your various claims about the number of nine-car IETs being used on off-peak duties on Oxford/Cotswold and Cheltenham services?
You have seemed entirely relaxed about the prospect of people having to stand for more than 20 minutes on IETs on what you deride as 'commuter' routes when demanding that nine-car sets be sent to run half-empty through Cornwall instead of covering duties like the 15.14 from Hereford (15.18 from December). All year round, it picks up a large number of passengers at Oxford at 17.30 who are heading to Reading and London, many of whom would be standing for a whole lot longer than 20 minutes if your demands were met.
Maybe you could now give this a rest until the new timetable beds in and there is some experience of how loadings through Cornwall adjust during the winter and over next summer to the structural changes in the timetable that Clarence Yard has pointed out.
