Doesn't Newquay need gauge clearance work for IEP? That's not on the CP5 work plan at the moment. Penzance wasn't on the core IEP routes at the start of CP5; by the time of the Hendy review Penzance, but none of the branches, had been added. So while the current SLC calls for at least one through train to London per day, will that continue?
My thought too
Portion working IEPs for these services (1452 Penzance-Par and 1506 Newquay-Paddington) sounds ideal, but what about the 1610 Par-Newqay? That would still need diagramming. Currently formed using the unit that came up from Penzance.
Such a major recast is planned on the Cornish Main Line that this question probably changes - though the question of where the stock goes / comes from before / after a break from a regular pattern remains an excellent one.
<advocate mode=devil>Whilst logic suggests that the longer (and long distance) train be used on the busier route, if the traffic on the quieter route at this time of day is mostly long distance, and on the busier route is mostly shorter distance, isn't it correct to run the long, long distance train on the quieter route just this once a day in order to provide something for through passengers. Remember you loose nearly half of them to rail if you make them changes, whereas the busier route already has a good variety of through long distance trains so there isn't that loss to rail - rather a transfer of passengers to trains that run an hour or two earlier or later</advocate>
150202 is gauge cleared all the way from Newquay into Paddington, I'm sure ...
