Delayed train with no explanation

Date: 2009-04-29
Journey Origin: Ascot
Scheduled Dep. Time: 10:25
Journey Destination: Waterloo
Estimated Delay: 14 minutes
Details of complaint: Big delay, and the train only stopped at Staines and then Waterloo. The only explanation from the platform staff was 'emergency engineering works'.
The guard didn't explain the revised stops until after the train had left Ascot, leaving a number of very angry people stuck on the train, who'd run from the platform to catch it.
Of course as the guard is locked away in the middle of these trains you can't actually ask him anything until the train stops somewhere and he gets out.
Oh, and even though it's 16 degrees outside the heaters were still on full blast in the carriage I was in.
