On the District Line today, just about to arrive at the platforms at
Earls Court and we stop just for a minute or so and an announcement
comes over the PA, "we are currently awaiting a platform to become
free, we apologise for this delay". The most ridiculous thing was
the delay was so short there was barely time for the announcement to
be played before we started again and arrived at the platforms.
Just seemed pointless to me.

Presumably when the driver started the announcement, he didn't know that the
train would be moving so soon. I don't see anything to criticise here.
