Where's the rest of the train?

Date: 2009-06-24
Journey Origin: Ascot
Scheduled Dep. Time: 09:40
Journey Destination: Waterloo
Estimated Delay: n/a
Details of complaint: Where's the rest of the train? 4 carriages instead of 8 just doesn't cut it - standing room only at Ascot, not even a third of the way in to Waterloo?
And what are those big expensive signs they've put up everywhere actually for? If you can list the time the train is expected, where it will stop - why can't the number of carriages be listed? Some warning that another of the crappy trains has broken down, and it's being replaced with half a train from another line, would be just a little helpful.
