Possibly due to the fact that a lot of the platforms along the 'Pompey Direct' can only hold a 5car 444 or an 8car 450, but on a Saturday you need more capacity than a single unit can offer. Therefore running an 8car 450 is simpler for the passengers as they only have to worry about short platforms at a few locations (for example Rowlands Castle) whereas if you ran a 10car 444 they would need to be in the front 5 coaches to alight at the majority of stations, causing confusion and unnecessary hassle for those who don't use the train often or otherwise unfamiliar with the route.Why do swt not run 444s to pompey on saturdays?
Interesting thanks for that. Any idea why this could be or has it always been the better stock has been needed for the weymouth routes on a Saturday? Apparently stopping services to Portsmouth via Eastleigh are 444s on Saturday which seems strange so in effect they could use 444s.
Problem is timetabling, which sees an inbound service from Portsmouth go back out of Waterloo on a service to Poole. I can't image customers West of Southampton being too pleased at having a service with no tables at the weekend.
