Going back to the SWR order being split into 60 x 10 car and 30 x 5 car, has anyone got an idea if the 5 car versions will see much use as individual units?
Is it likely for instance that they will nearly all (see below) run as pairs during the week, but the Saturday and/or Sunday timetables will see some routes reduce to single units, as we have seen recently with SWT's use of the 455s?
I'd also suspect that the future shuttle service Weybridge to Virginia Water might only use 5 car trains 7/7 - anyone agree with this possibility?
Anything more than a 4 car 450 or 5 car Aventra would seem a bit of an overkill for the Weybridge shuttles. Even if they were overcrowded, it is only a short journey. A 450 on the shuttle could make a lot of sense as it would be an easy way for some depots to keep up their Desiro traction knowledge once they are off Suburban work.
I guess the 5-car units could be used similar to the way the 458s are currently, with single 5 car units being used on some Off Peak and Weekend services.
