More unexplained delays

Date: 2009-07-02
Journey Origin: Ascot
Scheduled Dep. Time: 09:40
Journey Destination: Waterloo
Estimated Delay: 10 mins at Ascot
Details of complaint: The train was 7 mins late arriving, and then once it had shown up, it sat there on the platform. Everyone was on board, nothing going on that would delay it - the lights were green.
Eventually train moved off, but there was no explanation for why it was late or what the delay at the station was.
The rest of the journey was at a snail's place, and the train was seriously late arriving at Waterloo.
I missed a connecting train because of this - thanks guys! No communication from the guard or the platform information systems as to why it was so delayed.
Luckily I just missed the 09:10 from Ascot, as once again that was only 4 carriages and was standing room only.
I guess South West Trains feel no need to give out any information on late running and half-length trains, on the basis that the service is consistently poor so these things should be expected.
