And this was what the revised consultation option tried to resolve (retain xx35 ex Waterloo stopping pattern while splitting the xx05 at SOU all day with front portion limited stop to Poole), but this would have meant the loss of direct trains between stations west of Poole and east of Bournemouth (Pokesdown, Christchurch, New Milton).
Would it have worked doing it the other way around, having:
xx05 with similar stopping pattern as now - i.e. all stations west of Brockenhurst
xx35 fast to Southampton, then front portion doing current pattern of Brockenhurst, Bournemouth, Poole and some stations to Weymouth
xx35 rear portion can then do all stations Southampton to Poole - if current timetable was retained, it would fit nicely into the path of the Poole stopper after Brockenhurst (which could terminate at Brockenhurst to avoid the awkward 25 minute wait? Or detach off the xx05, again fitting neatly into current timings?)
That way:
- Weymouth gets its 2 fast trains to London
- Stations either side of Bournemouth directly connected by the xx05 (exept Totton, Ashurst & Beaulieu Road, which don't have a direct service to west of Poole currently)
- Potentially, a path Waterloo to Soton is freed up by 'splitting up' the Poole stopper (xx39 from WAT)
Does Weymouth need more than 1tph to London itself? It's not a very important place really.
Poole and Bournemouth of course do need more, and can turn 'inners' - but I feel like some Coastway-style shuttles might do the job for local service/frequency.
This was the thinking in SWR's Dec 2018 consultation - have 1tph Weymouth to Waterloo, 1tph stopping Weymouth to Portsmouth and 1tph Waterloo to Poole. Having Weymouth lose 2tph to London and smaller stations losing a direct London service caused such an outcry that it was changed to having the Portsmouth terminating at Bournemouth and extend the Poole to Weymouth.
So, Weymouth certainly
thinks it needs 2tph to London. Bear in mind that trains are only 5 coaches west of Poole (though some 8-car 450s ran for the Olympics IIRC?), so capacity on individual services is limited. And its MP clearly thinks even this is not good (or at least fast) enough.
Re coastway shuttles - I don't know how well they'd be used; the predecessor to Southern ran 1tph Bournemouth to Victoria via Chichester - ended up being cut back to Soton in the early 2000s, though unsure if this was because of low numbers. It only called at Brock and Bournemouth.
