Heard at Paddington yesterday (Monday 21st) for the 7.06pm Henley departure.. All those people rushing to join the train at the last minute (as instructed) were quite surprised to find it hadn't even made it into the station at this point..
As an aside the platform was about 10 deep people wise when it finally did arrive and looked like most unpleasant conditions on the train when it left (I decided against it)
