Especially for something that is not time-critical like setting off

But in my experience, the few times I have seen it happen, when the
guard gives a single ding after the train has set off, but is still
in the platform, the train has stopped pretty smartish (often quite
abruptly as though the driver has just thrown into 'emergency' rather
than a smooth stop)

Martin was referring to a "ding-ding" not a "ding".

Indeed I was. A single ding is an emergency: if the train has just set off,
it means that someone is half in and half out of the train or a slam door
has come open. THe driver needs to act first, and acknowledge after.

Responding to ding ding is not urgent: it doesn't matter if the train sets
off now or in 5 seconds' time, so there's time to acknowledge first.
