My experience in the Tube tells me that just one speaker blaring "MIND THE GAP" isn't enough.
At least two are needed, and, most importantly, the announcments must be slightly offset from one another, so that travelers are subject to a overlapping barrage of polite reminders, like so:
Zeppelin technology was simply overcome by another new technology -- film.
The spectacular explosion of the Hinderburg in 1937 was played and replayed in movie theaters across the world, horrifying the public and giving zeppelins a permanent reputation as dangerous and unsafe.
Zeppelins might have made a comeback, had it not been for those dramatic images.

MUH-MIND THE-UH GAP-AP.
MIND-IND UHTHE AP-GAP.
There's no call for that.
