While they are not bad now, railway station announcements used to be quite unintelligible in Melbourne. Often it was because of the announcers strong accent, but not always. The point is illustrated that it may have been a world wide problem, if you check out this clip from Monsieur Hulot's Holiday.
I was recently reminded of the scene by a friend who did a bit of up and down platform running at Flinders Street Station. Very M. Hulot, said the other friend.
Have you done the up platform, down platform dash to catch a train after a poor announcement or staff advice?
