Having worked on the platforms at Didcot, I can say the system works at Didcot and works well!
Every person I had ask 'when the next train to Paddington was' was told the time of the next one, if it happened to be the stopping service, this was explained to them and the time taken to get there given, funny old thing I never had anybody take up the offer of the stopping service, they would all wait for the next fast.
If people did turn up expecting to see a xx:55 London Paddington because they had seen it on line / timetable etc but on arrival at the station, could only see xx:55 Ealing Broadway, they would ask the staff and I refer you to above. Again, funny old thing they never complained about the stopping service being advertised as Ealing Broadway when it was saving themselves approx. 40 mins travelling time.
