Hmm, there's always the 2012 transport plan etc, I was only looking at it earlier to confirm that there will be no international trains stopping at Stratford during the games. Goes away, searches for a while, comes back having found a small section in one of many documents checked...
http://www.london2012.com/documents/oda-transport/pages-from-olympictransportplanpart2-7-18.pdfAll they say about Weymouth:
Weymouth Station will be the promoted as the ^venue station^.
The location of the venue offers relatively good accessibility with respect to public transport by rail, being served by two train operating companies. South West Trains operates the London Waterloo to Weymouth service. First Great Western operates the Bristol Temple Meads to Weymouth Service.
The rail capacity is limited due to line constraints (particularly the single track section of line between Dorchester and Moreton) and available power supply between Wareham and Weymouth Stations, however the ODA is currently investigating options to increase the rail capacity.
The choice for railway access station to the spectator viewing areas is limited to the main station within Weymouth.
The railway station is approximately 100 metres from the Esplanade.
Improvements to Weymouth Station^s forecourt area are being delivered by Dorset County Council^s Weymouth Transport Package.
IIRC▸ SWT▸ cannot run more than a single ten car train, or two five car, beyond Moreton at once.
I can't find any info about power supply improvements in any of the usual
NR» documentation, such as the route plan and
CP4▸ enhancement plan. The latter does however mention London area Olympic work, so I'm assuming Weymouth doesn't get any new infrastructure - and to think only a couple of years ago people were talking about track doubling AND power supply improvements...
I also think the current 2 tph frequency from Waterloo to Weymouth
is the increased frequency for the games - there isn't much hope of more, due to the single track section.
The Network Rail route plan seems pretty lukewarm too, and I don't think you can read much into it anyway, cos it discusses Weymouth and Wimbledon together:
The Olympics in 2012 will see events being held in Wimbledon and Weymouth but it is expected that
travel demand in relation to these events can be broadly accommodated within the current network
capability. Extra services may need to be provided at certain times, but, for example, Wimbledon
already sees high demand during the tennis fortnight so it is expected that regularly implemented
service strengthening will apply. Traction power supply issues between Bournemouth and
Weymouth may limit any increase in the number of electric trains which can be run during the games
period.
Having said all that, I'm not that convinced of the draw for spectators of offshore sailing - I wonder if those you see on TV aren't usually friends, family, other competitors waiting to go on, and coaches etc?
You can read up on squillions of improvements in Stratford though...
