I suppose my best bet is to watch the signals and see which one goes
green first, but you can't see both sets at the same time except when
standing at the very front. And I get the impression that the driver
starts closing the doors before the signals change. Are there any
other lights or clues I could be watching out for?

It's actually better to be towards the rear of the train, although
there is a gap between the platforms and trains due to a curve. There
is still a platform repeater on platform 3, which shows a yellow light
when the signal is red. The staff normally make announcements during
the evening peak regarding the first train to depart, but this is done
to the overbridge area, where customers who have entered the station
usually wait for the train information display. There is an upgrade
planned to the present train indicator board due at some point.
Drivers don't normally start to close the doors before the signal
changes, as it's far too easy to then start moving the train and end
up passing a signal at danger, not a situation anyone wants at that
complex junction!
