As there seem to be lots of people here with lots of knowledge about Cornwall and it's railways, I am hoping that someone can shed a bit of light on how the various trip workings in the Speedlink era were organised. I have searched through this forum and a number of books already but cannot find the sort of information I am after. For the period I am interested in, there seem to be three Speedlink arrivals at BZ (at approx. 0550, 0740 and 1215) and three departures (0930, 1520 and 2210). How would the traffic on these arrivals be tripped to the various destinations, and how would the loaded wagons be tripped into BZ for the various Speedlink departures? In other words, what might a typical day look like for BZ's fleet of 37s? Obviously some of them would be engaged on the Carne Point trains, and on that subject, how was that work programmed? I am guessing that a number of locos would set off at the start of the early shift to various points and somehow manage to get back for a shift change at some point. I suspect those in the know will be thinking, well, there was no such thing as a typical day, but if anyone can provide some information on how it all happened, I would be most grateful.
